Abstract: Study on RAKE-MMSE time domain equalizers are attempted for high data rate ultra wideband communication system. We 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. The proposed receiver combats inter-symbol interference by taking advantage of the Rake and equalizer structure. A semi analytical approach and Monte-Carlo simulation are used to investigate the BER performance of RAKE-MMSEreceiver on IEEE 802.15.3a UWB channel models. We show that for a MMSE equalizer operating at low to medium SNR's, the number of Rake fingers is the dominant factor to improve system performance, while at high SNR's the number of equalizer taps plays a more significant role in reducing error rates
