对图像进行DCT正反变换，可以在matlab里面观察正变换后的数据，达到数据压缩。(DCT pros and transform the image in matlab which observed data is transformed to achieve data compression.)

Here is a lumped parameter model of a hydraulic transmission line. The line is modeled by one, two, three, four and ten lump models. The simulation program presents the transient response in addition to experimental results.

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.

维纳滤波器用于自回归过程+噪声滤波，得到均方误差与滤波器维数，均方误差与自相关的关系。(Wiener filter for the the autoregressive process+ noise filtering, mean square error filter dimension, the mean square error autocorrelation relationship.)

这是一篇很好的有关信道估计的文章， 可以用来快速的了解信道估计的基本内容(and MAI induced by multiple-input, multiple-output channels. In particular, this article reviews the typical inverse filter criteria (IFC) based algorithm, super-exponential algorithm, and constant modulus algorithm along with their relations, performance, and improvements. Several advanced applications of these algorithms are illustrated, including blind channel estimation, simultaneous estimation of multiple time delays, signal-tonoise ratio (SNR) boost by blind maximum ratio combining, blind beamforming for source separation in multipath, and multiuser detection for direct sequence/code division multiple access (DS/CDMA) systems in multipath.)
