RESUMO

In this work the advantages of using channel information on convolutional codes threshold decoding is analised. Specifically, the advantages of using soft received values when transmiting binary symbols through a Gaussian channel is examined.Two algorithms, one proposed by Massey and another one, suboptimum, are compared against an implementation that to not account for the channel information. A better performance has been observed when the optimum Massey algorithm is used and a slightly inferior performance is observed for the sub-optimum algorithm, an indication of robustness of techniques that use channel information.
