Abstract

Viterbi decoders are used to decode convolutional codes.Using Viterbi alogorithm Viterbi decoder decodes a bit stream that has been encoded using convolutional encoder. The choice of asynchronous design was predicted due to its power and speed advantage. HREM is a combination of Trace Back Method(TBM) and Register Exchange Method(REM). HREM reduces the switching activity.There are two types of decision outputs, hard decision and soft decision. As soft decision output is having high error correcting capability than hard decision, accuracy can be increased. In this paper we are proposing a new approach of asynchronous design using HREM.The main aim of proposed method is to reduce power consumption.

Key Words

Convolutional encoder, Viterbi Algorithm, Viterbi decoder, asynchronous, power consumption, hybrid register exchange method, soft output decision.
