Communications Toolbox

Convolutional Coding Features of the Toolbox

The Communications Toolbox supports feedforward or feedback convolutional codes that can be described by a trellis structure or a set of generator polynomials. It uses the Viterbi algorithm to implement hard-decision and soft-decision decoding.

For background information about convolutional coding, see the works listed in Selected Bibliography for Convolutional Coding.
