viterbi
- 实现了卷积码的viterbi译码，软判决和硬判决均可实现，是从英文教学书上抄下来的。-Achieved viterbi decoding of convolutional codes, soft decision and hard decision can be realized, from the English teaching books, copied down.
viterbiDecoderConvolutionalCode
- Viterbi decoder for nonsystematic convolutional code. The encoder could be designed arbitrary through the generate matrix and parameter k. The number of row of generate matrix is output bits, and collom is constraint length. Parameter k is the number
viterbi
