一个matlab实现的image matting的代码。包括Possion matting等四种不同的matting算法的实现。(Achieved a matlab code image matting. Possion matting, such as including four different types of matting algorithm.)

说明：  m序列发生器(简单型码序列发生器-----simple shift register generator)(m sequence generator (a simple code sequence generator----- simple shift Regi ster generator))

源信号数目的估计在阵列信号处理中有很广的研究了，这个源程序是基于新一代通信环境下的源信号数目估计，如mimo——ofdm(detection the number of source signals for MIMO_OFDM)

说明：  使用MATLAB实现CDMA系统的RAKE接收机，并给出了合并后的系统性能。并给出将数字调制改成QPSK时修改后的程序。(RAKE receiver for CDMA system)

说明：  使用人工势场法实现避障的无人车路径规划，且具有较多注释说明(Artificial potential field method is used to realize obstacle avoidance path planning of unmanned vehicle, which has many explanatory notes)

区别去传统的傅里叶变换，对于非平稳信号而言，分数傅里叶变换是一个较好的方法，本程序实现了分数傅里叶变化对LPF类信号的估计。具有较高的学习价值(Different from the traditional Fourier transform, for non-stationary signals, fractional Fourier transform is a better method, this program implements the fractional Fourier transform to estimate the class LPF signal. It has higher learning value)

这是一个costas实现的QPSK解调器，这个解调器可以实现一个QPSK调制信号的解调！(it is about a demodulator for QPSK！)

simulation and software 的仿真代码第五章。 这是一本很好的通信系统仿真学习工具，国内几乎找不到原著。(simulation and software simulation code5. This is a very good learning tool for communication system simulation , domestic impossible to find the original . )
