Description: 卷积码的译码方法主要有两种：代数译码和概率译码。代数译码是根据卷积码的本身编码结构进行译码，译码时不考虑信道的统计特性。概率译码在计算时要考虑信道的统计特性。典型的算法如：最大似然译码、Viterbi译码、-Convolutional Decoding by two major ways : Decoding algebra, probability and decoding. Decoding is based on algebraic Convolutional Codes itself coding structure decoding, decoding not consider access to the statistical characteristics. Decoding in the calculation of the probability to consider when Channel statistical characteristics. Typical algorithms such as : Maximum Likelihood decoding, Viterbi decoding, Platform: |
