6种信号的调制识别，识别率在SNR<10是高达90 。非常好的程序！！！(a very good matlab program!)

说明：  实现了SAR成像点目标仿真中中RD算法的零斜视角成像，根据洪文翻译的Ian G. Cumming的《合成孔径雷达成像算法与算法》讲解的算法实现。(SAR imaging point target to achieve a simulation algorithm in RD zero oblique angle imaging, achieved according to Hung translation of Ian G. Cumming &quot synthetic aperture radar imaging algorithm and algorithm&quot to explain the algorithm.)

Converts a floating point value to IEEE 754 32 bit binary representation. Sign Bit: 1 Exp: 2 to 9 Frac: 10:32 Single-precision floating-point format is a computer number format that occupies 4 bytes (32 bits) in computer memory and represents a wide dynamic range of values by using a floating point. In IEEE 754-2008 the 32-bit base 2 format is officially referred to as binary32. It was called single in IEEE 754-1985. In older computers, other floating-point formats of 4 bytes were used. For example, the 32-bit floating point bit pattern 1 01111101 00101100000000000000000 is interpreted as the following: (− 1)1 × (1 + 0.34375) × 2(125–127) = -1.34375× 2− 2 = -0.3359375 ​

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been implemented for a 2x2 system. The reader can program other variations. The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.

说明：  Bpsk在瑞利衰落信道下的仿真模型。simulink实现。可以通过仿真看到瑞利衰落信道对于bpsk性能的影响。并且可以比较rayleigh信道和AWGN信道下bpsk的性能。(Bpsk in Rayleigh fading channel simulation model. Simulink achieve. Simulation can see Rayleigh fading channels for BPSK performance impact. And to be compared Rayleigh Channel and AWGN under BPSK performance.)

说明：  LMS自适应算法，可供大家理解LMS自适应算法(LMS adaptive algorithm, LMS adaptive algorithm for us to understand)

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第五高级编程应用(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the fifth high-level application programming)

Horn-Schunck optical flow method是光流法处理的一种经典方法。希望对学习光流的朋友提供帮助。(Horn-Schunck optical flow method is the optical flow method of treatment of a classic. I hope to learn optical flow of a friend to help.)

The aim of this application is to implement scalable mpeg type compression by varying DCT coefficients and finding minimum number of DCT coefficients that can give minimum acceptable quality.. This application only works for gray scale.

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)
