| 摘 要： | 根据信道转移特性的规律，本文提出一种采用非均匀量化区间的软判决Ｖｉｔｅｒｂｉ译码方案，对原有十六电平的均匀量化的量化区间进行修改，尝试了两种非均匀量化方案，计算机模拟表明：依据信道的统计特性合理的确定非均匀量化区间，不仅可以减少硬件实现的复杂性，而且可以以较少的量化区间取得更好的译码效果。

| Abstract: | This paper presents a Soft - decision Viterbi decoding with non - uniform quantification according to the channel measurement information. The uniform intervals of 16- level are revised and two non - uniform quantificated intervals are tried. The computer simulation shows: if non - uniform guantificated intervals are rationally determined according to the channel measurement information, the complicacy of the hardware can be reduced and the better decoding effects achieved with much less quantificated intervals. |
