SIMPLIFIED POLYNOMIAL-EXPANSION LINEAR DETECTORS FOR DS-CDMA SYSTEMS

The multistage linear receiver of Moshavi et al. was designed to appro ximate the decorrelating detector and the MMSE detector without calcul ating the inverse of the crosscorrelation matrix R of the spreading co des directly. However, it is complicated by the need to calculate a se t of weights using a procedure involving the inverting of a large matr ix. A modified structure is proposed to accomplish the same task witho ut the need for computationally intensive procedures such as matrix in version.
