soft Demapping 8PSK : LLR computation using Euclidian distance approach, Parallel-to-Serial converter, needs I and Q componets of 8PSK symbols at the input

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
