找到的一个比较实用的日历程序源码，用于开发与日期相关的程序，替代Calendar，实现其无法改变颜色等操作(To find a more practical calendar program source code, for the development of date-related procedures, alternative Calendar, realize that it can not change the color and other operations)

是用MATLAB作的SSB实现的解调与调制(MATLAB　　SSB)

求解二维圆柱绕流问题，涉及坐标变换，还有通量分裂，在变坐标系下直接数值模拟ns方程二维情况(Solving two-dimensional circular cylinder flow problem, involving the coordinate transformation, flux splitting, direct numerical simulation ns Fang Cheng Erwei situation in the change of coordinate system)

this is program for modulation in ASK and that is very usefull.

LMS、LMS/DFT、LMS/DCT、卡尔曼滤波、AR谱分析和小波变换的程序(Program LMS, LMS/DFT, LMS/DCT, Kalman filtering, AR spectral analysis and wavelet transform)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)

现代社会发展要求通信系统功能越来越强，性能越来越高，构成越来越复杂；另一方面，要求通信系统技术研究和产品开发缩短周期，降低成本，提高水平。这样尖锐对立的两个方面的要求，只有通过使用强大的计算机辅助分析设计技术和工具才能实现(Social development of modern communication systems require increasingly strong, the performance is getting higher and higher, which constitute more and more complex On the other hand, communications systems technology research and product development to shorten the cycle, reduce costs, improve the level. This in sharp opposition to the two requirements, only through the use of powerful computer-aided analysis and design techniques and tools can be achieved)
