This viterbi soft and hard decision decoding ...extremely useful and easy approach for BER .-This is viterbi soft and hard decision decoding ...extremely useful and easy approach for BER .

This document is about 16 QAM demapping of received data. But its a soft demapping method based Log likelihood ratio(llr). So results can be used as inputs for viterbi decoder or turbo decoder. It is very usefull to decrease BER for communication sys

Soft Output Viterbi Decoding algorithm is used for the soft decoding of iterative channel codes.

GSM Channel Equalization This application note describes the theory and implementation of GSM channel equalization and channel decoding algorithms using the Freescale MSC8126 Viterbi coprocessor (VCOP). It also examines the theory behind the soft o
