Comparative Study on Receivers Performance Using DFE and LE Equalizer for Uwb Communication System

Abstract

-In This paper comparison results are presented for receiver used for UWB communication system .we have taken in to account of impact of all the parameter such as Rake fingers and equalization tap on the error performance and SNR. Rake receivers can be employed since they are able to provide multipath diversity .another aspect is to combate the inter-symbol-interference(ISI) ,this distorts the transmitted signal. A semi analytical approach and mote-carlo simulation are used to investigate the BER performance of receivers on IEEE 802.15.3a UWB channel mode. we observe that the performance of MMSE Time domain equliser with DFE is high as compared to other receiver.
