Performance Analysis of UWB Communication Receiver in Multipath Environment Based on RAKE Receiver

Abstract

The paper contains the results of bit error rate (BER) performance research of the Rake receiver in multipath channel. The BER performance comparison with the non-Rake correlation receiver is presented, the method of estimation of BER performance of multipath components for the choice of optimal UWB wireless system parameters such as data rate, modulation scheme, duty cycle, pulse shape and multipath components assigned to Rake receiver fingers is proposed. Binary Pulse Position Modulation is employed as a modulation scheme.
