There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performance is stored in BER_awgn. 5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file. 6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable. 7] Run the simulation. To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray >>semilogy([1:8],BER_awgn(1:8), g* ) hold on semilogy([1:8],BER_ray(1:8), -.b* ) hold on grid on (There are two zip files in the folder.

超分辨率复原（分块处理） 将样本库中的高分辨率图象和低分辨率图象分别做分块处理，当新输入一幅低分辨率图象时，分成小块到样本库中寻找最匹配的高分辨率块，然后复原出高分辨率图象。(Superresolution recovery (block processing) for a sample of high-resolution images and low-resolution images respectively block , when the new importation of a low-resolution image, divided into small samples to find the most matching high-resolution block, then recovery from high-resolution images.)

按照GPS原理与接收机设计一书，应用matlab实现kalman滤波在ＧＰＳ中的应用(GPS receiver design in accordance with the principles of the book, the application kalman filter matlab realization of GPS applications)

水下图像的matlab程序，FCM水下图像聚类及图像增强matlab代码，非常有用(Underwater image matlab procedures, FCM underwater image clustering and image enhancement matlab code, very useful)

用matlab读取.dxf文件。本站原有代码dxf2coord_20.m中对于圆弧只能读出其圆心坐标及半径，缺少圆弧起始角及终止角，并不能在应用中实际用起来。修改后可以读出圆弧的起始角和终止角(the script can offer start angle and end angle of an arc,which are unable to access in an earlier script dxf2coord_20.m 。)
