Applying Asynchronous Techniques to a Viterbi Decoder Design

L.E.M.Brackenbury, M.Cumpstey, S.B.Furber, P.A.Riocreux


Viterbi decoders are used for decoding convolutional forward error correction codes in a large proportion of of digital transmission systems including mobile phones and digital television. For portable applications, the battery size and lifetime is of commercial importance as is the size of the electronics. Therefore, a low power, area efficient implementation is of commercial interest as a means of both lowering costs and extending the battery operating time
