Title
A new LDPC-STB coded MC-CDMA systems with SOVA-based decoding and soft-interference cancellation
Abstract
This paper analyzes several interference cancellation scheme applied to LDPC-STB coded MC-CDMA systems. 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, 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 schemes, concatenated with LDPC detectors can potentially provide significant capacity enhancements over the conventional matched filter receiver1.
