    Secure random linear network coding on a wiretap network2015In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 69, no 1, p. 467-472Article in journal (Refereed)
    Abstract [en]

    We develop a secure random linear network coding scheme on wiretap networks where a wiretapper can only eavesdrop on a limited number of channels. On one hand, by refining Lima's "locked coefficients" method and applying the approach of one-time pad, our scheme can well protect message packets without decreasing network throughput. On the other hand, by treating ciphertext as noisy symbols, inspired by the physical layer technique, and applying Shamir's secret sharing scheme, our scheme can successfully protect secret random seed without any forms of key exchange or secret channels. Compared to existing schemes, our scheme has minimum information overhead, independency of hash functions, and no restriction on global encoding kernel. Finally, we analyze the computational complexity of our proposed scheme and rigorously prove that our scheme can achieve secure network communication. (C) 2014 Elsevier GmbH. All rights reserved.

    Realisation of an Active Inductance for a Low Power High Bandwidth DC Power Line Communication Network Transceiver2010In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 64, no 10, p. 947-952Article in journal (Refereed)
    Abstract [en]

    An active inductor based on an improved gyrator circuit is proposed. The active inductor is developed to be implemented in a high impedance transceiver for a wearable DC power line communication network where requirements such as low power consumption, high bandwidth and numerous nodes support are prioritized. A load isolation step is introduced to ensure the stability of the active inductance's size on different load currents. The proposed gyrator circuit is analyzed and optimized by means of theoretical calculations. The theoretical results are then verified by simulations and experiments in the frequency range up to 10 MHz.

    Impact of Doppler spread and adaptive modulation on TCP throughput in Rayleigh fading channels2010In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 64, no 11, p. 1082-1089Article in journal (Refereed)
    Abstract [en]

    A number of wireless systems have recently adopted adaptive modulation (AM) schemes to improve its efficiency. In this letter, our aim is to study the impact Doppler spread and adaptive modulation has on transmission control protocol (TCP) throughput in Rayleigh fading channels. We consider a finite state Markov channel (FSMC) model, which is a useful model for analyzing radio channel with nonindependent fading. Furthermore, we use a Markov model for TCP evolution and evaluate the TCP performance by computer simulations. In our simulations we have compared the TCP Reno scheme with TCP Tahoe scheme. The results indicate that a large Doppler spread leads to lower TCP throughput due to more frequent transitions of channel states and modulation schemes which make it difficult for the TCP congestion control mechanism to accommodate the dynamic link characteristics.

    A remark on the computation of Fock functions for negative arguments2008In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 62, no 4, p. 324-326Article in journal (Refereed)
    Abstract [en]

    The Fock functions are mainly used in diffraction theory. A problem with some of these functions is that accurate numerical computation of integrals with certain exponentials is needed. An integration contour that essentially solves this problem is discussed.

    An extension of the Fock current distribution functions2012In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 66, no 7, p. 540-546Article in journal (Refereed)
    Abstract [en]

    The standard Fock functions that are the point of departure for this study are used in diffraction theory to describe the surface current on perfectly conducting convex scatterers. They are fairly accurate near the shadow boundary and in the shadow. There is also a reformulation in terms of these functions that describes the field in the lit region. In this study, a uniform counterpart to these functions is obtained for cylindrical geometry by means of integral representations. The numerical aspects of the evaluation of these integrals are discussed. High accuracy is achieved, also for the lit region. Asymptotic approximations for the uniform functions are obtained in the high frequency limit. These expansions could provide the same accuracy as the integral representation inside the lit domain of the scatterer.

    Accurate hybrid techniques for the method of moments in 2D2016In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 70, no 5, p. 539-543Article in journal (Refereed)
    Abstract [en]

    The integral equations of electromagnetic scattering can be solved numerically by means of the method of moments. This normally leads to a linear system with a dense matrix. Higher order basis functions such as B-splines is a means to improve the accuracy.

    For smooth convex scatterers and high frequencies the oscillatory behaviour of the solution can be used to reformulate the integral equation. A sparse matrix can be obtained by modification of the integration path used in the integral equation.This is quite straightforward for the two-dimensional TM case, since the currentdecays rapidly in the shadow in that setting.

    In order to increase sparsity and handle the standing waves that are prominent for the TE case, the shadow region can be treated separately, in a hybrid scheme based on \emph{a priory} knowledge about the solution. An accurate method to combine solutions in this hybrid scheme is presented.

    Half-select free bit-line sharing 12T SRAM with double-adjacent bits soft error correction and a reconfigurable FPGA for low-power applications2019In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 104, no May, p. 10-22Article in journal (Refereed)
    Abstract [en]

    This work presents a half-select free 12T SRAM cell with Data-Dependent Feedback Cutting approach to improve the write ability and isolated read path to enhance the read stability. The enhanced read and write ability is 1.95×" role="presentation"> and 2.84×" role="presentation"> larger respectively than that of the conventional 6T cell at 0.4 V. The half-select free behavior of proposed cell using the cross-point read/write structure facilitates the bit-interleaving memory architecture to effectively reduce the multi-bits soft error occurrence. The incorporated PMOS stacking effect in inverter pairs of the proposed cell offers the reduced leakage power which is 0.59×" role="presentation"> to that of 6T, at 0.4 V supply. To further minimize the leakage power at array level, the bit lines between two adjacent cells have been shared that consumes only 0.38×" role="presentation"> leakage power than that of the conventional 6T array for a 1 KB macro. Moreover, a Reconfigurable FPGA architecture is proposed for low power applications. The simulated static and active power consumption of 12T SRAM based reconfigurable FPGA is 0.22×" role="presentation"> and 0.45×" role="presentation"> when compared with the regular 12T FPGA. Finally, a Double Adjacent-bits Error Detection and Correction (DAEDC) scheme is suggested for the proposed bit-interleaved 12T SRAM array, to reduce the soft error effects.

    A reconfigurable and adaptive routing method for fault-tolerant mesh-based networks-on-chip2011In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 65, no 7, p. 630-640Article in journal (Refereed)
    Abstract [en]

    High reliability against undesirable effects is one of the key objectives in the design of on-chip networks. This paper presents a very low cost fault-tolerant routing method to tolerate faulty links and routers in mesh-based Networks-on-Chip. This new algorithm can be dynamically reconfigured to support irregular topologies caused by faulty components in a mesh network. In addition, it is a distributed, adaptive and congestion-aware routing algorithm where only two virtual channels are used for both adaptiveness and fault-tolerance. The proposed routing method has a multi-level fault-tolerance capability and therefore it is capable to tolerate more faulty components in more complicated faulty situations with additional hardware costs. The network performance, fault-tolerance capability and hardware overhead are evaluated through appropriate simulations and syntheses. The experimental results show that the overall reliability of a Network-on-Chip is significantly enhanced against multiple component failures with only a small hardware overhead.

    Closed-formed distribution for the SINR of MMSE-detected MIMO systems and performance analysis2018In: AEU - International Journal of Electronics and Communications, ISSN 1434-8411, E-ISSN 1618-0399, Vol. 97, p. 16-24Article in journal (Refereed)
    Abstract [en]

    In this paper, we investigate the error performance of multiple-input multiple-output (MIMO) wireless communications systems using minimum mean-square error (MMSE) detection. Particularly, a new closed-form statistical distribution for the output signal-to-interference-plus-noise ratio (SINR) of MMSE receiver is derived, for independent Rayleigh fading channels. The expression for the distribution of SINR is shown to be a linear combination of gamma distributions and polynomial of where xis the SINR. Base on the derived distribution for the SINR, closed-form and approximated expressions for the symbol error probability (SEP) of quadrature amplitude modulation (QAM) and phase shift keying (PSK) signaling are obtained, respectively. The derived SINR density and SEP are valid for arbitrary number of transmit and receive antennas. Furthermore, a reduced complexity approximation is introduced to obtain the SINR distribution and SEP performance of MMSE-Detected MIMO Systems with a large number of antennas. The provided simulation results confirm the validity of our theoretical analysis for both the SINR and SEP. All rights reserved.
