OFDM系统中，部分传输序列PTS的算法源码((Orthogonal Frequency Division Multiplexing PTS)

说明：  基于matlab实现的循环谱估计算法，可以对具有循环平稳特点的信号进行参数估计，如直扩信号和周期调制信号(The cyclic spectrum estimation algorithm based on Matlab can estimate the parameters of signals with cyclostationary characteristics, such as DS-SS signals and periodic modulated signals)

配置STM32串口并接收和播发数据，需自己注意STM32的引脚连接(Configuring STM32 serial port and receiving and transmitting data)

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.)
