正弦信号利用小波分析都分辨路分析的方法去除噪声，分别处理其中的高频和低频系数(Sinusoidal signals are resolved using wavelet analysis method for removing noise path analysis, which respectively deal with high frequency and low-frequency coefficients)

说明：  该程序给出了OFDM信号以及频谱分析，也插入了保护间隔(the procedure given OFDM signal and spectrum analysis, insert a protective partition)

说明：  异步电动机三相逆变器供电时的PWM控制仿真模型，MATLAB/simulink仿真(Three-phase induction motor when the inverter PWM control model, MATLAB/simulink simulation)

This file can be used for generation of LTE PRACH preambles as per zadoff chu sequences

清华大学章毓晋老师图像分析最后一次作业答案(The answer for the last homework of image analysis by Yujin Zhang, Tsinghua univ.)

The travelling salesman problem (TSP) asks the following question: Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the origin city? It is an NP-hard problem in combinatorial optimization, important in operations research and theoretical computer science.

说明：  this is simple signal processing matlab code

数学实验中的最速落径问题 A,B是不在一条铅垂线上的两点，在链接A,B两点的所有光滑曲线中，找出一条曲线，使得初速度为零的质点，在重力的作用下，自A点下滑到B点所需的时间最短 (Mathematical experiment steepest drop Path problems A, B is not a vertical line of two points, the link A, B two points in all the smooth curve, to find a curve, the initial velocity of the particle is zero, gravity role, and since the point A to B points decline in the time required for the shortest)
