QAM调制软比特解调，能够更准确进行解调。-Soft bit QAM modulation and demodulation, can be more accurately demodulated.

使用matlab的LDPC编码，映射为64QAM，软解调(ldpc coding whic is very good)

极化码所需要的16-QAM的调制与解调，只需要输入对应的比特，输出也为对应的比特(The modulation and demodulation of 16-qam required by the polarization code only requires the corresponding bit input and the corresponding bit output)
