Abstract [en]

High data rates are highly demanded now-a-days in most of the communication systems such as audio/video broadcasting, cable networks, wireless networks etc. This can be achieved using Orthogonal Frequency Division Multiplexing (OFDM), which is a bandwidth-efficient method. However, the major drawback of the OFDM technique is its high Peak-to-Average Power Ratio (PAPR). Due to this high PAPR, the amplified signal is distorted if its peaks are not controlled. This thesis investigates a PAPR reduction technique called Fourier Projection Algorithm (FPA). During the thesis, the FPA algorithm is successfully designed to reduce the PAPR in the OFDM systems to avoid the clipping. The results of the FPA algorithm show that the efficiency of the system depends on the throughput, the complexity, and Tone Rate Loss (TRL) of the system. The simulations are first carried out in SIMULINK and MATLAB environments and later on it is synthesized on coarse-grained reconfigurable fabric platform.
