P3.18. An analog signal xa(t) = sin (100πt) is sampled using the following sampling intervals. In each case plot the spectrum of the resulting discrete-time signal. Ts= 0.1 ms, Ts= 1 ms, Ts = 0.01 Sec

说明：  MATLAB编写的仿真小程序,关于STEP CONCROL的,仿真出CONTROL执行后的图形(MATLAB simulation prepared by the small program on STEP CONCROL. Simulation out CONTROL implementation of the graphics)

ARMA时间序列法预测模型，有示例数据及注释等(autoregression----moving average)

The program RANDOM_WALK_2D_PLOT plots the trajectories of one or more random walks. The program RANDOM_WALK_2D_SIMULATION plots averaged data for any number of random walks that each use the same number of steps. The data plotted is the average and maximum of the distance squared at each time step. The average distance squared should behave like the number of time steps.

利用常用四阶龙格-库塔公式求初值，再利用汉明公式、米尔恩公式和改进的四阶亚当斯隐式公式及常用的四阶龙格-库塔公式求解其余的数值解求解常微分方程初值问题，并计算它与精确解的误差(Use of commonly used fourth order Runge- Kutta initial value to the Formula, and then use the Hamming formula, Milne formula and improved fourth-order implicit Adams formula and the commonly used Runge- Kutta formula for solving the numerical solution for solving the remaining ordinary Differential Equations, and calculate the error it with exact solutions)

EMD主程序，将EMD的核心思想应用Matlab程序实现，其他相关程序可再联系本人。(EMD main program, the core idea EMD Matlab program. other related procedures can be linked himself.)

基于二发二收MIMO系统的半盲信道估计，其中main为主程序，其它为子程序(Second, land-based MIMO system made of two semi-blind channel estimation, in which main-based process for the subroutine other)

说明：  多抽样理论关于抽样，内插，及有理数抽样等应用。特别的对仿真结果结合多抽样理论进行了详细的分析，(Multirate Signal Processing using in sampling and interpolation and analyse in detail.)

此文件是一测试信道相关性的文件，可以用来对比(This file is the file of a test channel correlation，Can be used to compare。 )

matlab原理图，很全很不错的的作业，是matlab入门必看等(Schematic matlab, matlab entry, etc.)
