描述了一种新的混和ARQ方式传输方案。将一个码字重复J次得到一个新的码字——原码字的组合码,并用某种规则进行译码可望得到正确码字,从而解决了信息传输中有效性和可靠性的矛盾,减少了重传次数。定性比较了几种差错控制方式,详述了自适应重传混和ARQ方式传输的基本原理,推导了组合码的译码算法,并且举例将这种自适应重传混和ARQ方式与传统的ARQ方式进行了比较。
A new hybrid ARQ scheme transmission scheme is described. A code word is repeated J times to obtain a new code word - a combination code of the original code word, and decoding with a certain rule is expected to obtain the correct code word, so as to solve the contradiction between validity and reliability in information transmission, Reduce the number of retransmissions. Qualitatively compared several error control modes, described the basic principle of adaptive retransmission and hybrid ARQ mode transmission, deduced the combination code decoding algorithm, and for example, this adaptive retransmission hybrid ARQ mode and the traditional ARQ mode Compared.
