设信号 ，用 对x(t)采样得x(n)，是否会发生频谱混叠？现利用FFT分析其频谱。 1．编程绘制该信号的波形。 2．若令N=16，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 3．令N=1024，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 4．分析2、3的运算结果。 设计调试报告要求： 1．工作原理简述； 2．设计思路； 3．难点及解决方法； 4．设计、调试结果及分析； 5．程序文本及操作步骤。(based signal used to x (t) in the sample x (n), whether there will be a spectrum aliasing? FFT analysis is the use of their spectrum. 1. Programming mapping of the signal waveform. 2. If so N = 16, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 3. Order N = 1024, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 4. Analysis of two, three computational results. Design debugging reporting requirements : 1. Principle outlined; 2. Design; 3. Difficulties and solutions; 4. Design, debugging and analysis of results; 5. Text and operating procedures steps.)

基于music算法的均匀圆阵方向估计，算法测试好用，可以下载(Uniform circular array direction estimation based on music algorithm. The algorithm is tested well and can be downloaded.)

用蒙特卡罗仿真研究一个通信系统的误比特率BER。假设通信系统满足条件：信源输出的数据符号是相互独立和等概的；在发射机中没有进行脉冲形成；信道是AWGN信道(Using Monte Carlo simulation of a communication system bit error rate BER. Suppose communications systems to meet the conditions: the data source output symbols are independent, and so almost the no pulse in the transmitter in the form channel is AWGN channel)

实现了小小去噪，与其他去噪方法相比取得了良好的效果(denoising based on wavelet)

svt is algorithm that calculate a matirx from the part of it s elemets . it is can be applied to image processing when part image was lost.是一个算法，知道部分矩阵元素，计算整个矩阵的方法。该方法主用是借助奇异值分解和Bregman算法，可很快完成计算。可以用于图像数据缺损的情况。

说明：  以truetime-1.5为例说明truetime工具箱的安装方法，很实用！！(An example to truetime-1.5 truetime toolbox installation method, it works! !)
