摘要
由于无线信道的时变、高误码等特性,码率可变的RCPT码是比较理想的信道编码方式。结合ARQ(automatic repeat request),RCPT码得到了比较广泛的注意。但是RCPT码的译码算法比较复杂,影响了RCPT码的进一步应用。针对这一问题,提出了一种基于ARQ的RCPT码的简化译码算法。这种算法利用不同先前译码的信息,快速地得到重传后的译码结果,大大降低了RCPT码译码的复杂度。
For the characteristics of wireless channel such as time-variety and high BER, the rate adjustable RCPT code is good for channel coding. Combined with ARQ, RCPT is widely noticed. But the decoding algorithm of RCPT is too complex to let RCPT code more advanced used. A simplified algorithm based on ARQ is proposed. This algorithm uses the former decoded information to get the decoded result after ARQ. It can greatly reduces the complexity.
