通过调用Perron-Frobenius定理的一种形式的“最小和”半环,我们得到了一个联合界的咬尾码的迭代译码性能。该界限表明,对于高斯信道,当且仅当码的最小“伪距离”大于普通最小距离时,迭代解码将是最佳的,至少对于高SNR是这样。
By invoking a form of the Perron-Frobenius theorem for the "min-sum" semi-ring, we obtain a union bound on the performance of iterative decoding of tail-biting codes. This bound shows that for the Gaussian channel, iterative decoding will be optimum, at least for high SNRs, if and only if the minimum "pseudo-distance" of the code is larger than the ordinary minimum distance.
