Linearly Constrained Constant Modulus Algorithm Based Blind Multi-user Detection for MC-DS-CDMA Uplink

摘要：

A linearly constrained constant modulus algorithm (LCCMA) based blind adaptive multi-user detection (MUD) is presented for MC-DS-CDMA systems. In order to eliminate the MAI, the LCCMA adaptive filter is used on each subcarrier via blind signal processing method. Theoretical analysis and simulation results show that it performs the same as training sequence minimum mean square error MUD. Therefore, it can be considered as a compromise candidate for MC-DS-CDMA high data rate multi-user access scenario.
