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.)

说明：  对三路单音信号合成模拟话音信号进行PCM编码，并采用BPSK调制，通过AWGN信道，接收端采用BPSK相干解调和PCM译码，恢复原模拟信号(PCM coding is used to synthesize analog voice signals from three monotone signals. BPSK modulation is used to restore the original analog signals through AWGN channel. BPSK coherent demodulation and PCM decoding are used at the receiving end.)
