卷积码的编译码。信源为随机产生数，进行软判决译码。-And decoding convolutional codes. Source of random numbers, soft decision decoding.

卷积码软判决的译码程序，采用的是维特比译码算法-Convolution code soft decision decoding program, using the Viterbi decoding algorithm

本目录包含ADSP-2191单核例程，实现半速率软判决GSM Viterbi译码器。(This directory contains an example ADSP-2191 single-core subroutine that implements a soft decision half-rate, soft-decision, GSM Viterbi decoder.)
