提出了基本相关解码方法的两种修改。其中之一产生非穷尽的最佳字解码算法,其复杂性取决于代码的“投影”结构。然后修改该算法以产生第二解码算法,该算法虽然不是最佳的,但具有更简单的复杂性。讨论了 AWGN 信道的应用,并给出了 (24, 12) 和 (31, 15) 码的性能曲线。
Two modifications of the basic correlation decoding approach are presented. One of them yields a nonexhaustive optimum word decoding algorithm whose complexity depends upon the "projecting" structure of the code. This algorithm is then modified to yield a second decoding algorithm which, while not optimum, has simpler complexity. Applications to the AWGN channel are discussed and performance curves are given for (24, 12) and (31, 15) codes.
