摘要 针对Turbo码MAP(MaxaProbability)译码算法的特点 ,对其量化方式进行了分析、讨论与仿真 ;着重讨论了量化范围、量化级数、均匀和非均匀量化等因素对译码器接收比特、前后向递推度量、附加信息和输出似然值的影响 ;分析了相应的译码性能 ; The quantification pattern for the MAP decoding algorithm of Turbo codes is studied.The effect of the bound,level and other parameters for quantification are discussed. The good performance of nonuniform quantification is claimed and a reasonable quantificational method is obtained.
