Abstract

Abstract:

Compared to the characteristic of ultra-wideband (UWB) signal and multi-path propagation within indoor environment, a low complexity RAKE receiver scheme was expatiated, which debases system sample rate. Moreover, an algorithm based on minimum mean square error (MMSE) parameter estimation was proposed as well to reduce the finger number and to improve performance. The performance of simulation receiver bit error rate (BER) shows that the algorithm is adaptive to pulse based UWB system when narrowband interference and inter symbol interference (ISI) exist.

Key words: ultra-wideband, wireless person area network, minimum mean square error, RAKE receiver
