卷积码译码算法改进 实现Conv.(2,1,9)的编码、软判决滑动窗维特比译码，其生成多项式为G0=561(八进制),G1=753(八进制)，调制方式为BPSK，信道为AWGN，比较不同的译码深度对译码器性能的影响-convolutional code decoding algorithm to improve achievement Conv. (2,1,9) of the Code, Soft Decision sliding window Viterbi Decoder, genera

典型的Turb。码是一类并行级联的系统卷积码，当交织长度足够长时，其性能可逼 近仙农限。-Typical Turb. Code is a class of parallel concatenated convolutional codes of the system, when the cutting length for long enough, its performance can be close to Shannon limit.
