分析了利用卷积编码和利用码组合的第二类选择重传混合ARQ(Automatic-Repeat-Request，自动重传请求)方案。利用码组合，在对数据分组的连续解码尝试时，用于纠错的解码器对该分组的所有接收序列的组合进行操作，而不是像在传统的类型II混合ARQ方案中那样仅对最近接收的两个序列进行操作。分析和计算机模拟表明，即使在很高的信道误码率下，使用码合并也可以获得显著的吞吐量。>；
An analysis is presented of the selective-repeat type II hybrid ARQ (automatic-repeat-request) scheme, using convolutional coding and exploiting code combining. With code combining, at successive decoding attempts for a data packet, the decoder for error correction operates on a combination of all received sequences for that packet rather than only on the two most recent received ones as in the conventional type II hybrid ARQ scheme. It is shown by means of analysis and computer simulations that with code combining, a significant throughput is achievable, even at very high channel error rates. >
