• The performance of the hybrid-ARQ scheme with a convolutional code, in which the retransmission criterion is based on an estimated decoding error rate, is evaluated for moderately time-varying channels. It is shown by computer simulations that the simple average diversity combining scheme can almost attain the same performance as the optimally weighted diversity combining scheme. For the whole and partial retransmission schemes with the average diversity combining, the theoretical bounds of throughput and bit error rate are derived, and it is shown that their bounds are tight and the treated schemes can attain a given error rate with good throughput for moderately time-varying channels. Furthermore, the throughput is shown to be improved by the partial retransmission scheme compared with the whole retransmission scheme.
