Throughput improvement of oversampled WiMAX receiver in frequency selective channel

Abstract

As an attempt to improve throughput of WiMAX system, the oversampled WiMAX receiver is presented in this paper. Oversampling samples each transmitted symbol more than one time. Thus, several signal sequences which contain different information about channel may be obtained at the receiver. This study presents throughput of the oversampled WiMAX system that obtained by simulation over a realistic channel model and by experimental tests. Since the performance of oversampled system is very much depends on channel conditions, realistic channel model and experimental study are essential to exhibit the realistic performance benchmarks. Simulation and experimental results clearly show that oversampled WiMAX receiver significantly outperforms the spectrum efficiency of the conventional system.
