基于卷积信号的MIMO系统盲信号估计，运用卷积的方法进行盲信道估计(Convolution-based MIMO system, blind signal signal is estimated using the method of convolution-blind channel estimation)

说明：  关于Matlab课件，便于大家的学习和工作，是很好滴(On the Matlab software, to facilitate everyone' s learning and work, is a good drop)

录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))

精通matlab6.5的源代码，很好的一本 学习matlab的书(Matlab6.5 proficient in the source code, a good book to learn matlab)

有关卡尔曼滤波的文档，很有用处，大家传阅这看吧！！！！！！！！！！！！！(about kalman filter)

说明：  MATLAB的编译器代码，都是visual c/c++代码(MATLAB compiler code, are visual c/c++ code)

本例用五点差分法求解一个二阶偏微分方程，其间用Jacobi迭代求解(This example uses a five-point difference method for solving second order partial differential equations, during which the Jacobi iterative)
