Abstract

Abstract:

The usage of the unicast wireless link is improved via combining the incremental redundancy versions of multiple data streams, which are requested for retransmission. Before channel decoding, retransmission data streams are respectively detected from the composite stream by the belief propagation (BP) algorithm and combined with soft information buffered at the receiver during the previous transmission phase. Moreover, by the BP algorithm, the correctly recovered data streams are cancelled from the composite stream to improve the detection performance of other erroneous streams. For multi-stream transmission over the unicast wireless link, compared with the traditional automatic repeat request (ARQ) scheme, about 10% spectrum efficiency gain can be obtained by the proposed multi-stream ARQ. Meanwhile, the complexity increase is less than 22%.

Key words: wireless telecommunication systems, channel coding, automatic repeat request, network coding, belief propagation
