Abstract

This paper presents a blind MMSE near-far resistant receiver for a DS/CDMA system by combining reduced-length space-time MMSE (STMMSE) receiver with blind constant-modulus-aIgorithm (CMA) approaches. The reduced-length STMMSE receiver with training sequences is studied first. Two CMA approaches which are capable of combating both ICI and MAI without stringent power control are proposed to generate training sequences for the STMSE receiver
