Subband Signal Separation

Abstract [en]

In wireless communication,the transmitted signals arrive at the receiver will be subjected to multipath propagation,i.e.the signals will be received with different time delays and attenuations.It is therefore not enough to use only a spatial receiver since such a receiver can not exploit the multipath properties. A temporal receiver,on the other hand, works well or multipath situations but does not utilize the spatial information which is of vital importance in multiuser systems.Thus,a combined spatial and temporal receiver structure can utilize multipath,spatial distribution and independence properties of the multiple sources.Such a spatial-temporal receiver structure is usually computationally complex. In this paper a subband signals separator is presented to reduce the required complexity without a significantly reduction in performance. The subband signal separator will be compared with its fullband equivalent using performance measures as the complexity and mean-square-error. Simulation results show that up to 82 % reduction in the computationally complexity with only a slightly degradation in mean square error performance.
