NOTE: This function modifies the BUTTONDOWNFCN of axes in the input list, and their children. However, it will not modify any object whose buttondownfcn is nonempty.

说明：  计算两个时间序列的传递熵，返回双个方向的值(compute the transfer entropy)

Matlab版俄罗斯方块，个人一直认为，这个游戏或者说这个程序很经典！ 如果你能掌握这个程序，你对Matlab的外功已经不成问题，回家修炼一下内功，就能毕业了！！ 不说别的，先来玩玩，别忘了把音箱打开！感受儿时的乐趣 程序作者：Pascal Getreuer (Matlab version of Tetris, individuals have always thought that this game or that the program was classic! If you can master this program, you have no problem Matlab' s external work, home practice about internal strength, we can graduate! ! If nothing else, the first to play, do not forget to turn on speakers! Experience the fun process of childhood: Pascal Getreuer)

由于卫星与用户接收机二者的连线方向上存在相对运动，因此引起了载波和伪码的多普勒效应，再加上接收机晶体震荡频率漂移和卫星时钟频漂等原因。接收机实际接收到的卫星载波中心频率一般不再等于信号被发射时的标称频率，这就需要接收机在载波频率一维对信号进行搜索。同时，由于卫星到接收机的距离时刻变化，加上接收机始终相对于GPS时间的偏差又并不固定，因而接收信号的伪码相位值也在改变，所以接收机也要在码相位一维对信号进行搜索。扩频信号的捕获是一个对目标信号频率域和相位域进行的二维搜索过程。(Because of the relative motion between the two of the satellite and the user receiver, the Doppler effect of the carrier and pseudo-code is caused, and the frequency drift of the oscillation of the receiver crystal and the frequency drift of the satellite clock are added. The frequency of the satellite carrier center that the receiver actually receives is generally no longer equal to the nominal frequency of the signal being transmitted, which requires the receiver to search the signal in one dimension of the carrier frequency. At the same time, because the distance between the satellite to the receiver is changed, the deviation of the receiver always relative to the GPS time is not fixed, so the pseudo code phase value of the received signal is also changing, so the receiver also searches for the signal in the code phase. The acquisition of spread spectrum signal is a two-dimensional search process for the frequency domain and phase domain of the target signal)

瑞利衰落信道（Rayleigh fading channel）是一种无线电信号传播环境的统计模型。这种模型假设信号通过无线信道之后，其信号幅度是随机的，即“衰落”，并且其包络服从瑞利分布。(Rayleigh fading channel, Rayleigh fading channel) is a statistical model of radio signal propagation environment. This model assumes that the signal through a wireless channel, its signal amplitude is random, or "decline", and its envelope obey Rayleigh distribution. )

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)
