We propose a low complexity H-ARQ utilizing bit interleaved coded modulation (BICM). Our aim is to improve the reliability and bandwidth efficiency of wireless communications using high rate H-ARQ enabled by the proposed BICM option. This type-II hybrid ARQ generates incremental redundancy and diversity by varying the bit-to-symbol mapping during retransmission without relying on FEC design. The joint detection at the receiver through maximum likelihood demapping before error correction is… CONTINUE READING
