matlab中tic与toc函数联合进度条使用例子(tic toc function matlab in combination with the use of examples progress bar)

一个关于OFDM信道估计的Matlab源程序

改进的OMP_channel_estimation信道估计(improved OMP channel estimation)

Generates a lognormally faded signal with multipaths (10) and multiple scattering (5)

仿真了OFDM中的SLM方法 ，并附有仿真图形，对于初学PAPR的朋友可有用(Simulation of the OFDM in the SLM method, together with simulation graphics, for a friend can be useful for beginners PAPR)

Structured covariance estimation. The routine takes a covariance matrix as input and returns the Toeplitz matrix that lies closest to it, in the sense that it minimizes the Kullback-Leibler divergence between the two. Input must be a real, square, symmetric and positive semi-definite matrix.

给你一个非常大的整数x，(-10^400 <=x<= 10^400)，请统计x的每一位，分别输出9,1,2出现的次数. Input 一个大整数 Output 一共三行，第一行是9出现的次数，第二行是1出现的次数，第三行是2出现的次数。 Sample Input 912912912910915902 Sample Output 6 5 4(Statistical figures)

说明：  包里有直流电动机的simulink模型，适合于直流电机的调速，启动仿真(Bag has simulink model of DC motor, suitable for DC motor speed control, start simulation)

多普勒二维频谱分析，通过载入数据得出而为多普勒频谱(2D Doppler spectra)

射频电路设计，微波设计中常常用到的smith原图，本程序利用MATLAB编程画出smith原图，可以帮助射频电路设计，比如画等功率匹配圆，等阻抗圆，等反射系数圆等。(RF circuit design, microwave design is often used smith artwork, this program using MATLAB to draw smith original programming that can help RF circuit design, such as painting and other power matching round, such as impedance circle, so the reflection coefficient circle and so on.)
