| Abstract: | A novel receiver is proposed in this paper that uses the blind adaptive multi-user detection(MUD) technique to deal with the presence of multiple-access interference(MAI) and inter-symbol interference(ISI) in terms of high speed time-hopping ultra-wideband(TH-UWB) system.The receiver firstly adopts constrained recursive least squares constant modulus algorithm(RLS-CMA) to conduct adaptive decorrelation for eliminating MAI and ISI,and then uses projection approximation subspace tracking with deflation(PASTd)... |
