Abstract
This paper analyzes several interference cancellation schemes applied to STBC-TCM for MC-CDMA. In these systems, a linear MMSE detector is conventionally used to reduce interference generated by multipath, multiuser, and multiple antennas propagation. To obtain further performance improvements (measured in terms of bit error rates), a more efficient SOVA-based iterative MMSE scheme is considered. This receiver performs soft interference cancellation for every user based on a combination of the MMSE criterion and the turbo processing principle. It is shown that these block space-time concatenated with coding channel detectors can potentially provide significant capacity enhancements over the conventional matched filter receiver.
