Line 142:

A Viterbi decoder uses the Viterbi algorithm for decoding a bitstream that has been encoded using [[forward error correction]] based on a convolutional code.

The [[Hamming distance]] is used as a metric for hard decision Viterbi decoders. The ''squared'' [[Euclidean distance]] is used as a metric for soft decision decoders.
