Implements soft-decision Viterbi decoding for a rate 3/4 code over an AWGN channel using Simulink(R).
The Viterbi decoder block from the Communications Blockset is enhanced to optimally support punctured codes.

The attached BERTool session file compares the BER performance as the number of bits are varied for the soft decision with the performance for unquantized inputs. The model file is set-up to support additional runs.
