宽带DOA的TCT算法，从本网站下载之后，发现程序有点问题而不能运行，对线性调频信号的生成做了小改动后，程序可以正常运行(The TCT algorithm for broadband DOA，the code is download from this website previously, but find a problem and the program can t run , then modify the code of linear FM signals generation, the program can run)

是一个对mimo连续相位调制系统的均衡程序，利用MMSE准则来实现。(Mimo is a phase modulation system for a balanced program, using the criteria to achieve the MMSE.)

greedy_method.m为为贪婪算法程序。所得结果为局部最优，可能不是全局最优的。(greedy_method.m greedy algorithm program. The results obtained for the local optimum, may not be globally optimal.)

在采样点之间的频率响应是由各采样点的加权内插函数叠加而形成的，因而有一定的逼近误差。该误差大小取决于理想频率响应的形状，理想频响特性变化越平缓，内插值越接近理想值，逼近误差越小；反之，如果采样点之间的理想频响特性变化越陡，则内插值与理想值之间的误差越大，因而在理想滤波器不连续点的两边，就会产生尖峰，而在通带和阻带就会产生波纹。用频率采样法设计的实际滤波器频率响应如图1所示。由图1可知，实际滤波器的阻带衰减取决于内插函数第一旁瓣幅度值的大小，其大小决定了所设计的滤波器的阻带性能。(Interpolation function superimposed between sampling points of the frequency response is weighted within each sampling point and the formation of, and thus have a certain degree of approximation error. The size of this error depends on the shape of the ideal frequency response and the ideal frequency response characteristic change is more gentle, interpolated and more close to the ideal value, the smaller the approximation errors Conversely, if the sampling point between the ideal frequency response characteristics of the steeper the change, and then the interpolated the larger the error between the ideal value, and thus in the ideal filter both sides of the discontinuity point, will produce spikes occurs ripple in the passband and stopband. Actual design frequency sampling filter frequency response is shown in Figure 1. Figure 1 shows, the actual filter stopband attenuation depending on the interpolation value of the size of the first side-lobe amplitude of the function that determin)

程序是基于元胞自动机的交通模型，主要是针对单车道、单车变数运动的描述(Program is based on cellular automaton traffic model for the description of the movement of bicycle paths, cycling variables)

一种fourier的快速变换，计算结果比matlab里的fft节省一半空间(A Fourier transform of fast, the calculation results of FFT than matlab save half space)

基于matlab的通断键控调制模块，跟通信原理书上的2ask调制原理类似，在调用时，需要在主函数中加入调制信号，和进制数，一般是2(Matlab on-off keying modulation of the module, with the Communication Theory book 2ask similar modulation principle, in the call, there is a need to add in the main function of modulation signal, and the hexadecimal number, typically 2)
