Multi Function Viterbi Decoder
The VA08VA is a low complexity 16, 32, 64 or 256 state error control decoder using the maximum likelihood Viterbi algorithm.
Overview
The VA08VA is a low complexity 16, 32, 64 or 256 state error control decoder using the maximum likelihood Viterbi algorithm. The decoder is designed for maximum flexibility, allowing it to decode various communications standards, as well as custom coding solutions. The VA08VA is an improved version of the VA08V offering 6-bit or 8-bit input quantisation, longer and more flexible traceback lengths and options for decoding terminated or tail-biting convolutional codes.
