全数字解调下16QAM信号的频偏估计的TD-GG算法实现。TD-GG算法是在TD和GG算法基础上提出来的，有较大的频偏估计范围和较好的估计精度，很好的解决了传统的非数据辅助频偏估计算法中估计范围和精度不能兼顾的问题，而且这种算法易于实现。(Digital demodulation under the 16QAM signal frequency estimation TD-GG algorithm. TD-GG algorithm is based on the TD and the GG algorithm is proposed, and have greater range and better frequency estimation of estimation accuracy, a good solution to the traditional non-data aided frequency offset estimation algorithm to estimate the range and accuracy not take into account the issue, and this algorithm is easy to achieve.)

QPSK的编译 设定噪声为高斯白噪声，对2ASK、2FSK、2PSK、2DPSK等各种调制方式及相应的主要解调方式下（分相干与非相干）的误码率进行统计，并与理论值进行比较，以图形方式表示误码率与信噪比间的关系。(QPSK compiled Set the noise is Gaussian white noise, right 2ASK, 2FSK, 2PSK, 2DPSK variety of modulation and demodulation mode corresponding to the main (sub-coherent and non-coherent) error rate statistics, and with the theoretical value comparison, a graphical representation of bit error rate and SNR relationships.)
