Forney algorithm

The Forney algorithm is a computational method used in coding theory, specifically for decoding convolutional codes. It provides an efficient way to find the most likely transmitted sequence given a received sequence, which may contain errors due to noise in the communication channel. Here are some key points about the Forney algorithm: 1. **Purpose**: The Forney algorithm is designed to decode convolutional codes by using a soft decision or hard decision approach based on the Viterbi algorithm's path metrics.
