Description: 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 systems. In addition, QPSK, 64QAM etc. demappers can be derived based on this document. Platform: |
