Viterbi decoder - Computer Definition
A decoding algorithm developed in the late 1960s by Andrew Viterbi that is used to decode a particular convolutional code. Viterbi decoders have been the most effective way to decode wireless voice communications in satellite and cellphone transmissions. Viterbi outputs a 0 or a 1 based on its estimate of the input bit. See CDMA, convolutional code and turbo code.
