A two-stage CMA-based receiver for blind joint equalization and multiuser detection in high data-rate DS-CDMA systems.

A two-stage CMA-based receiver for blind joint equalization and multiuser detection in high data-rate DS-CDMA systems.

The paper deals with the problem of blind mitigation of intersymbol interference (ISI) as well as multiple-access interference (MAI) in asynchronous high data-rate direct-sequence code-division multiple-access systems. A blind adaptive multiuser receiver based on the constant-modulus algorithm (CMA)...
