Chase译码算法的两种改进

Two Ways of Improvement of Chase Decode Algorithm

对Chase2算法提出了预估计试探法及奇偶校验法两种改进方法。模拟计算表明,与原算法相比,改进后的算法对译码性能没有影响,同时大大缩减了译码时间,降低了译码复杂度。

In this paper, two ways of improvements of Chase2 algorithm are made, namely the pre - test estimates test and the parity check. Simulation shows that the algorithm does not affect the decoding performance, while greatly reducing the decoding time and the decoding complexity compared with the original Chase2 algorithm.
