一个很好的MATLAB源代码——OMP，OMP算法的改进之处在于：在分解的每一步对所选择的全部原子进行正交化处理，这使得在精度要求相同的情况下，OMP算法的收敛速度更快。(A good MATLAB source code-- OMP, OMP algorithm improvement lies in: every step of the decomposition of orthogonalization processing all of the selected atoms, which makes the accuracy requirement of the same circumstances, the OMP algorithm s convergence speed is faster. )

Quadratic Thresholding and Auto-Adaptive LUM Filter

Modulation test for OFDM : This is a set of five (5) codes about COFDM (Coded Orthogonal Frequency Division Multiplexing) and coding schemes such as Convolutional, BCH, Reed Solomon (RS) and Low Density Parity Check (LDPC). The study uses an OFDM signal over an AWGN Channel with white Gaussian noise model, and calculate the Bit Error Rate wich is plotted.

人工加入椒盐噪声，进行中值滤波去噪,可以自己加入不同密度的椒盐(Artificial adding salt and pepper noise, median filtering denoising, you can add your own salt and pepper different densities)

基于傅里叶变换和匹配追踪的信号分解的一种新方法(Based on FFT and MP signal decomposition)

在matlab下利用simulink搭建模块，对典型信号如正弦波、方波、三角波、锯齿波、白噪声以及叠加波形的时域信号进行频谱（幅值谱）特性分析。(Module in matlab simulink structures, such as sine, square, triangle wave, sawtooth wave, white noise, as well as the time-domain signal waveforms superimposed spectrum (amplitude spectrum) characteristics of a typical signal.)

The example included here is a simple temperature conversion module that takes user-supplied temperature values specified in either degrees Fahrenheit or degrees Celsius and converts them to the other scale. The example demonstrates how to use the MATLAB® Builder™ JA API to handle temperatures in various different formats (scalars, matrices, cell arrays, and structs).

matlab实现字符的识别，matlab实现字符的识别，(number recognition)

Modulation and demodulation ASK. At the beginning, we create the digital signa (1 and 0), after we do the modulation, add noise and demodulation. At the end we do the reconstruction of the signal.
