利用Matlab编程实现对lena.bmp灰度图象进行QF=50和QF=40的压缩和解压缩，比较二者的PSNR，并且利用霍夫曼编码模拟信道中传输图象。通过了Matlab2009A测试。(Using Matlab program to compress and decompress the gray image Lena.bmp at QF = 50 and QF = 40,as well as comparing the result of two situation.Then using Huffman coding analog channels transmitted images. Adopted Matlab2009A test.)

its usage is in computer vision

双站交叉定位误差展示程序 产生观测数据 假设被定位对象匀速地从A点(dx1,dy1)运动到B点(dx2,dy2)，单位：km 使用速度输入V(km/h)，则dx2=V*t，t为观测时长(h) dy1=dy2=R，目标距离 假设采样时间间隔为1h(Bistatic cross-positioning errors show program)

This is learning Compressed sensing and best K-term Approximation method.

TEST_FBMPC Demonstrates how to construct a signal according to the signal model, and recover the signal using the FBMP algorithm by calling the function FBMPC_FXN

移频法实现啸叫抑制，通过对回声信号做移频，使得回声信号加上输入信号不会再某一频点能量过大产生啸叫(Frequency shift method to achieve howling suppression, echo signals by frequency shift do so echo signal plus input signal will no longer produce a certain frequency can be excessive howling)

采样点分别为16和256时的频谱和高分辨频谱分析图(Sampling points 16 and 256 respectively when the frequency spectrum and high-resolution spectrum analysis chart)
