Description: 16QAM因其高频谱利用率而被第三代移动通信增强型技术HSDPA采用。由于Turbo译码需要软信息输入，因此，解调输出需要计算比特软信息（LLR）。本文分析了LLR理论算法并在此基础上导出了简化算法。-16QAM its high spectral efficiency have been enhanced third-generation mobile communication technology HSDPA use. Turbo decoding requires soft information as input, therefore, need to compute soft output demodulation information (LLR). This paper analyzes the LLR theory based on the algorithm derived in this simplified algorithm.

Description: 对16QAM调制方式软解调，我们分为以下几个步骤进行：
⑴产生取值为0、1的随机数，作为16QAM调制的输入二进制序列；
⑵根据16QAM的星座图，按照输入序列分为I和Q两路进行映射，定义映射规则为00 －3，01 －1，11 1，10 3；
⑶产生一组高斯白噪声序列并分别叠加到映射后信号的实部、虚部；
⑷进行软解调。
-Soft demodulation of 16QAM modulation, we divided into the following steps: (1) to produce values for the 0,1 random number, and 16QAM modulation of the input binary sequence (2) according to the 16QAM constellation, according to the input sequence is divided into I and Q, two-way mapping, define the mapping rules for 00-3,01-1,11 1,10 3 (3) generate a set of white Gaussian noise sequence and were superimposed on the signal mapping the real part and imaginary part (4) conduct soft demodulation.
