Future wireless communication systems will require high data-rates in multiuser environments. Multicarrier code-division multiple-access (MC-CDMA) has emerged as an attractive technique for broadband communications, offering efficient utilization of bandwidth and robust performance in multipath channels. In this paper, coded downlink MC-CDMA is combined with the concept of LST architectures. Suboptimal receiver with soft co-antenna interference (CAI) cancellation is utilized and the performance of the system is evaluated in frequency-flat and frequency-selective fading channels. The results demonstrate that by using multiple-input multiple-output (MIMO) antenna system with coded LST transmission and iterative detection and decoding (IDD) at the receiver, the throughput and error rate performance can be significantly improved over the conventional single-input single-output (SISO) system.
