ACS for viterbi (r=1/2, pol=[133,171])

硬判决viterbi译码的硬件实现，通过verilog语言。采用回溯的方法。回溯深度为16.-Hard decision viterbi decoding in hardware, through the verilog language. A retrospective approach. Back depth is 16.

ACS UNIT FOR VITERBI DECODER function: It will add-compare-select the branch matric hence it will help to find the minimum path matrics which is necessary for viterbi decoding-ACS UNIT FOR VITERBI DECODER function: It will add-compare-selec

This an ACS unit which can be used in log-map algorithm as well as viterbi algorithm-This is an ACS unit which can be used in log-map algorithm as well as viterbi algorithm
