Comparision Study of Time Domain Equalization Technique Using Ultrawide Band Receivers Performance for High Data Rate WPAN System
For high data rate ultra wideband communication system, performance comparison of Rake, MMSE and Rake-MMSE receivers is attempted in this paper. The authors have taken into account of impact of all the parameters such as the effect of the number of Rake fingers and equalizer taps on the error performance by combating ISI are the major focus of the research. The bit error rate performances are investigated using semi analytical approach and Monte-Carlo simulation on IEEE 802.15.3a UWB channel models. A detail study on UWB channel model (IEEE 802.15.3a) is carried out using four channel models CM1- CM4. Simulation results show that the bit error rate probability of rake-mmse receiver is much better than Rake receiver and MMSE equalizer.
