Blind receiver for MIMO SC-FDMA communications

Because SC-FDMA (Single Carrier Frequency Division Multiple Access) is with the desirable characteristics of OFDMA and the low PAPR (Peak-to-Average Power Ratio) of single-carrier transmission schemes, it has been adopted as the uplink transmission scheme in 3GPP LTE to approach the demand for data transmission rates and error performance. By combining multiple-input multiple-output (MIMO) techniques with the SC-FDMA modulation scheme, MIMO SC-FDMA systems can achieve high data rates over broadband wireless channels. In this paper, we propose the iterative multiuser detection scheme for the low-density parity-check (LDPC) coded MIMO SC-FDMA communication systems. Some simulation examples for uplink scenario are given to demonstrate the effectiveness of the proposed schemes.
