MMSE-SIC-turbo receiver for CDMA-MIMO system

Multiuser detection and turbo coding are two key techniques for wide-band code-division multiple-access (CDMA) systems. Multiple input multiple output (MIMO) is one of the most powerful enhancing technology of HSDPA. In this paper, a new MMSE-SIC-turbo receiver is proposed for the CDMA-MIMO system model, which combines the multiuser detection, soft input soft output (SISO) decoder and multiple antenna processing technology. It can significantly suppress the multiple access Interference (MAI) and multiple antennas spatial interference. Simulation results demonstrate that the proposed receiver outperforms the ZF-PIC and RAKE-BLAST receiver in 3GPP
