Viterbi code

In the 1960s, Prof. Dr. Andrew J. Viterbi published a decoding algorithm named after him, which is still used in convolutional codes today.

The Viterbi code is based on an estimation of the reception sequence. In doing so, the Viterbi algorithm selects from all possible code sequences the receive code sequence that has the smallest Hamming distance. This is the code sequence that differs only slightly from the received sequence. For this evaluation, a metric was introduced to examine the receive code sequence for bit locations.

Bit errors can be corrected with the Viterbi code.
