International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Soft-decision correlation decoding with retransmission requests for block codes
is proposed and the resulting performance is analyzed. The correlation decoding rule
is modified to allow retransmission requests when the received word is rendered
unreliable by the channel noise. The modification is realized by a reduction in the
volume in Euclidean space of the decoding region corresponding to each codeword.
The performance analysis reveals the typical throughput - reliability trade-off
characteristic of error control systems which employ retransmissions. Performance
comparisons with hard-decision decoding reveal performance improvements beyond
those attainable with hard-decision decoding algorithms. The proposed soft-decision
decoding rule permits the use of a simplified codeword searching algorithm which
reduces the complexity of the correlation decoder to the point where practical
implementation is feasible.
