这封信认为，非二进制线性分组码的迭代解码算法，其中擦除和错误解码是由硬判决接收序列和给定的测试模式的总和给定的输入字进行。提出了一种新的迭代译码算法测试模式选择方法。仿真结果表明，在加性白色高斯噪声信道下，基于该方法的测试码译码算法比传统的纠错和纠删译码迭代次数相同的迭代译码算法具有更好的误码性能。
This letter considers an iterative decoding algorithm for non-binary linear block codes in which erasure and error decoding is performed for input words given by the sums of a hard-decision received sequence and given test patterns. We have proposed a new selection method of test patterns for the iterative decoding algorithm. Simulation results have shown that the decoding algorithm with test patterns by the proposed selection method provides better error performance than a conventional iterative decoding algorithm with the same number of the error and erasure decoding iterations over an additive white Gaussian noise channel using binary phase-shift keying modulation.
