高阶psk软解调的比特软信息简化计算方法，已经经过验证-High psk soft demodulation bit soft information simplified calculation method has been validated

calculating bit error rate in hamming code using soft decoding

The combining rules considered in this study are the OR hard combining rule, AND the hard combining rule, the Equal Gain Soft combining rule and the two-bit quantized (softened hard) combining rule. For all combining rules, the detection performance,
