PERFORMANCE EVALUATION OF AN OVERSAMPLED RAKE RECEIVER
01 January 1994
The adaptive RAKE receiver can be used in spread spectrum systems to combine the separate signal energies received due to multipath propagation effects. This paper presents an analytical performance evaluation of the average BER of an over-sampled RAKE receiver on a Rayleigh fading channel, and a comparison with asynchronous architecture. It is shown that over-sampling achieves a significant BER performance improvement. The channel estimator architecture of the over-sampled receiver is also presented
