提出了一种新的混合自动重传请求(ARQ)方案,该方案使用补充格码进行重传。在该方案中,补充码被设计为补偿用于先前传输的网格码的平方自由距离(d/sub free//sup 2/)。在接收机处,由相同的维特比解码器组合和解码相干编码的码字。与传统的网格编码混合ARQ方案相比,该方案在重传时提供了改进的(d/sub free//sup 2/),在传统的网格编码混合ARQ方案中,相同的编码方案用于所有传输。
A new hybrid automatic repeat-request (ARQ) scheme that uses supplementary trellis codes for retransmission is described. In this scheme, supplementary codes are designed to compensate for the squared free distance (d/sub free//sup 2/) of the trellis code used for the previous transmission. Differently encoded codewords are combined and decoded by the same Viterbi decoder at the receiver. This scheme provides improved (d/sub free//sup 2/) upon retransmission compared with that provided by the conventional trellis coded hybrid-ARQ scheme where the same coding scheme is used for all transmissions.
