利用matlab编程，比较软阈值和硬阈值收缩方案的去噪效果。通过了Matlab2009a的测试。(Using matlab programming, comparing the denoising shrinkage results of two methods between soft threshold and hard threshold program. Testing by Matlab2009a.)

说明：  非正弦信号的波束形成程序，和利用相位的常规波束形成不同，非正弦信号的波束形成首先匹配滤波，提取包络，然后延时相加，(Non-sinusoidal signal beamforming process, and the use of conventional beam-forming phase is different from non-sinusoidal signals in the first match beamforming filtering, envelope extraction, and then add delay,)

获取信号的强弱，非常好用，欢迎大家下载，好了不说了(Get signal strength, very easy to use, welcome to download, well, do not say)

TD-SCDMA小区搜索最为关键的sync-dl码同步的确定过程，即搜索DwPTS。(TD-SCDMA cell search of the most critical sync-dl code synchronization process of determining that the search DwPTS.)

基于matlab的OFDM仿真程序； 我再论坛找了很多OFDM的代码和文章,但总有遗患,为什么呢原因是大部分只有简单的映射,IDFTDFT变换等等,但主要的同步和信道估计去没有人提出来,甚至做出来.. 现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFTDFT,同步(时间频率同步)和信道估计,以及频率偏移的估计等一系列代码.(Based on the OFDM matlab simulation program I' ll find a lot of forums and articles OFDM code, but there are left suffering, why because most only simple mapping, IDFTDFT transformation, etc., but the main synchronization and channel estimation to no one proposed, and even do it .. and now I finally found a copy of it in the form FUNCTION, Reproduction of OFDM mapping, IDFTDFT, synchronous (time and frequency synchronization) and channel estimation, and the estimated frequency offset a series of code.)

行程编码的matlab实现。编码后的图像存储在变量E中,该变量是一个三纬树组,前两纬表示起始像素的横、纵坐标，第三纬表示该行程的颜色值。(Matlab coding realize itinerary. Encoded image is stored in the variable E, the variable is a three-wai Tree Group, the former two-wai express start pixel horizontal, vertical coordinates, the third weft express the color values of the trip.)

自编的FASTICA程序，简明实用，并附带两个子程序以及WAV文件，(FASTICA staged by the procedures, concise and practical, and with two subroutine and WAV documents,)
