Abstract A semi-blind multi-user constant modulus receiving system for downlink MIMO MC-CDMA system is proposed. The received signals are pre-processed before constant modulus detection, then the MIMO receiving system is transformed into several SISO receiving systems. The received signals are detected by SISO modulus algorithm. The improved method reduces the influence of multi-user interference and multi-path interference. It improves the detection performance obviously.
