AWGN信道下Turbo码误比特率模型 在实验基础上，通过曲线拟合等数学工具，得到加性高斯白噪声信道条件下，信道编码采用turbo码，通信系统端到端的误比特率经验模型。

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
