You can use it to simulation OFDM in BPSK,QPSK and 8PSK in AWGN channel.You can see the symbol error rate and bit error rate from these simulation.

广义互相关函数来确定两个信号的时延差，时延定位相关程序(Generalized cross-correlation function to determine the time delay difference between the two signals, the delay positioning procedures)

说明：  路径规划仿真，运用蚁群算法，利用MATLAB软件搭建二维地形环境(Path planning simulation, using ant colony algorithm, using MATLAB software to build two-dimensional terrain environment)

说明：  该方法自适应地将一个复杂的非平稳的多分量信号分解为若干个瞬时频率具有物理意义的乘积函数（Product function,简称PF）之和，其中每一个PF分量由一个包络信号和一个纯调频信号直接求出。包络信号就是该PF分量的瞬时幅值，而PF分量的瞬时频率则可以由纯调频信号直接求出，进一步将所有PF分量的瞬时幅值和瞬时频率组合，便可以得到原始信号的完整的时频分布。(This method adaptively decomposes a complex non-stationary multi-component signal into the sum of several product functions (PF) with physical meanings at instantaneous frequencies, where each PF component consists of an envelope signal and a pure The FM signal is directly obtained. The envelope signal is the instantaneous amplitude of the PF component, and the instantaneous frequency of the PF component can be directly obtained from the pure frequency modulation signal. Further, the instantaneous amplitude of all PF components and the instantaneous frequency are combined to obtain the complete original signal. Time-frequency distribution.)
