Multistage MMSE receivers for ultra-wide bandwidth impulse radio communications

Abstract

A reduced-rank receiver based on the multi-stage Wiener filter (MSWF) is proposed for multiple-access interference suppression for ultra wideband time-hopping spread spectrum radio in multipath channels. The proposed reduced-rank MSWF receiver provides performance superior to that of the classical RAKE receiver with similar complexity, and comparable to… (More)
