本文将文献[1]中超码的软判决思想应用到硬判决译码,建立了基于子码的硬判决译码器,从而展示了一条新的译码途径。对 Golay(24,12,8)码,本文找到了三个易于译码的子码:C_1(24,5,8)、C_2(24,6,8)和 C_3(24,8,8),并给出了寻找更大子码的方法。与文献[2]的方法相此较,本文的方法更利于用计算机编程实现。
This paper applies the soft decision idea of super-code in [1] to hard decision decoding, and establishes a hard decision decoder based on sub-code, which shows a new way of decoding. For Golay (24, 12, 8) codes, we find three easy-to-decode subcode: C_1 (24,5,8), C_2 (24,6,8) and C_3 And gives a way to find a larger subcode. Compared with the method of [2], this method is more conducive to computer programming.
