Abstract

In this paper, we propose an oversampled WiMAX receiver as an attempt to improve throughput of WiMAX system. In communication, oversampling is a technique that a signal is sampled with a higher sampling frequency than its original bandwidth at the receiver side. Thus more signal sequences, which is received through different paths, may be obtained compare to system with conventional sampling. These additional sequences generate diversity. This study theoretically analyzes an oversampled wireless communication system in case of capacity with outage over Rayleigh distributed flat fading channel and presents throughput of the oversampled WiMAX receiver that obtained by simulation over a realistic channel model and by experimental tests. Since the performance of an oversampled system very much depends on the channel conditions, realistic channel model and experimental study are essential to exhibit realistic performance benchmarks. Theoretical analyzes, simulations and experimental results clearly show that the oversampled receiver significantly outperforms the spectrum efficiency of the communication system.
