We analyze the performance of Rake receiver for Ultra Wideband system using Exponential-Lognormal multi-path statistical propagation channel model, which is based on extensive measurements in diversified Residential & Commercial environments. We evaluate the link performance of an UWB system using sub-optimum Rake receivers, which are based on either partial combining (PRake) or selective combining (SRake). The receiver SNR distribution statistics generated using standard cluster model and realistic exponential-lognormal model are compared for their relative performance. We investigate average bit error performance of commonly used Binary data modulation. Through semi-analytical evaluations of the Average Bit Error Probability (ABEP) and distribution of output SNR, we show that the simple PRake receiver is almost as good as the SRake for optimum number of fingers.
