Diversity combining techniques for bandwidth-efficient turbo ARQ systems

A type-I hybrid-ARQ scheme using multiple turbo codes is proposed. It uses turbo coded bit interleaved modulation for high bandwidth efficiency. The structure of parallel concatenated codes is exploited for diversity combining.
