ABSTRACT:
A method and apparatus for decoding received data signals using a Viterbi algorithm. To reduce the time required to decode a data signal, the system expands k received data vectors into nk vectors where n is smaller than m, m being the number of levels of the received data signal. Thereafter, k vectors are chosen from the nk expanded vectors and a "cost", defined herein is determined for each of said k vectors. The most likely identity of the received data signal is then determined on the basis of the computed costs.
