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

This file includes matlab source code for the Uncoded QPSK + Coded QPSK with Viterbi (Hard decesion) decoder.
