一本matlab学习书籍，包括入门到精通，还有simulink等，北航出版。(A matlab learning books, including entry to the master, as well as simulink, etc., Northern Publishing.)

说明：  本程序给出了qpsk调制的源码程序，具有一定的参考价值( this program shows the qpsk modulation,from this program we can understand the process of qpsk modulation more .)

高级变换的fft，dft代码实现，包括结果的绘图(fft and dft realization)

BPSK SNR vs BER graph simulation awgn channel

sobel filter for image processing

此函数包含了IBP算法的matlab源码程序，共享给大家共同学习(This function includes the IBP algorithm matlab source program, to share common learning)

matlab视频读取函数,用matlab处理视频文件,代码量较少.处理较容易.(matlab video read function with matlab processing video files, less the amount of code. deal easier.)

说明：  采用Matlab对信号进行四层分解与重构，合成一个文件更有利于理解Matlab功能(use Matlab to finish your signal processing)

（1） 数据源：随机产生752*8bit作为数据源 （2） 按照DTMB的能量扩散初始相位和生成多项式来产生伪随机数据并对原始数据源进行加扰 （3） 加扰后的数据直接进行解扰，观察误码率的值，验证加扰算法 （4） 按照DTMB标准构造BCH（1023，1013）来实现BCH（762，752）信道编码器和解码器，并观察其误码率是否为0来验证其正确性。 （5） 最后把能量扩散和BCH编码级联，接收端把BCH解码和解扰级联，观察其误码率，验证正确性。 ((1) Source: randomly generated 752* 8bit as data source (2) in accordance with the energy of the initial phase and the diffusion DTMB generator polynomial to generate a pseudo-random data and the original data source scramble (3) the scrambled data is directly descramble, the bit error rate of the observed values, verification scrambling algorithm (4) In accordance with DTMB standard configuration BCH (1023,1013) to achieve the BCH (762,752) channel encoder and decoder and observe its error rate is 0 to verify its correctness. (5) Finally, the energy dispersal and BCH coding cascade, the receiving end of the BCH decoding and descrambling cascade observed error rate, to verify the correctness.)
