Abstract

Abstract

The semi-blind Constant Modulus (CM) algorithm which applied in the Multi-User Detection (MUD) of CDMA is studied. This approach fully utilizes all known users information, performs not-blind detector to suppress the interferes within the cell, and exploits blind detector to suppress the inter-cell interference. Compared with the blind CM algorithm and the decorrelating algorithm, the proposed semi-blind CM algorithm exhibits better SIR and BER performances and it is more robust when the system is heavily loaded.
