16QAM数字通信信号的调制解调程序，尽可能的仿真实际的通信系统(16QAM modulation and demodulation digital communication signal process, as far as possible the actual communication system simulation)

按照一定的规则，对一定的样品进行分类的程序(According to certain rules, certain procedures for the classification of samples)

说明：  利用延迟-相加法对波达方向进行估计，程序简明易懂，适用于初学者。(using delayed- add method to estimate DOA, easily understandable for beginners.)

The demo shows two nonlinear interference cancellation methods - Zero-Forcing and Minimum-Mean-Square-Error - with symbol cancellation and compares their performance with the Maximum-Likelihood optimum receiver.

This file does the detection of transitions in a video by comparing the levels of histogram intensity between two consecutive frames. It shows a plot with the high levels of intensity, and the frames where transitions take place.

异步电动机反接制动，与陈伯时电机拖动课程内容相似(Asynchronous motor reverse braking Emulator)

非常实用的普朗克公式的计算代码,使用MATLAB编写(Planck equation very practical computing code，Using MATLAB prepared)

lms预测算法源程序，数字信号处理，雷达信号(LMS algorithm of the source program ，Digital signal processing)

matlab下对pcm编码进行模拟.可以进一步帮助理解编码过程(right pcm Matlab simulation code. Can help further understanding of the encoding process)

给出了信号压缩通常的变换-量化-编码函数。DHT函数为离散DHT变换，是FFT变换的近似，其正反变换相同，克服了FFT复系数不利于存储的缺点。LLMAX函数给出了某x序列在固定比特下的最佳量化输出。熵编码函数为霍夫曼编码。(Gives the signal compression usually transform- quantitative- coding function. DHT DHT discrete transform function, the FFT transform approximation, the same positive and negative transformation, overcoming complex FFT coefficient is not conducive to storage shortcomings. LLMAX function x is given a fixed bit sequence in the optimum quantized output. Entropy coding function as Huffman coding.)
