Vitterbi Decoding Algorithm
· An efficient search algorithm
· Performing ML decoding rule.
· Reducing the computational complexity.
· Generate the code trellis at the decoder
· The decoder penetrates through the code trellis level by level in search for the transmitted code sequence
· At each level of the trellis, the decoder computes and compares the metrics of all the partial paths entering a node
· The decoder stores the partial path with the larger metric and eliminates all the other partial paths. The stored partial path is called the survivor.
