OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

说明：  用于从图像中提取不同大小的块，采样可选为重叠，不重叠和随机，以及由块恢复图像的三个函数(Used to extract from the image blocks of different sizes, optional sampling overlapping, non-overlapping and random, and by block to restore the image of the three functions)

GSP算法的matlab实现，可查看算法效能，进行相关实验(GSP algorithm matlab realize, you can see algorithm performance, conduct experiments)

matlab实现用双线性插值法放大和缩小图像(Zooming and Shrinking Images by Bilinear Interpolation (a) Write a computer program capable of zooming and shrinking an image by bilinear interpolation. The input to your program is the desired size of the resulting image in the horizontal and vertical direction. You may ignore aliasing effects. (b) Download Fig. 2.19(a) and use your program to shrink this image 1024 x 1024 to 256 x 256 pixels. (c) Use your program to zoom the image in (b) back to 1024 x 1024. Explain the reasons for their differences. )
