数字通信系统的基本调制方式的matlab仿真程序(Digital communication system of basic modulation of matlab simulation program)

利用元胞自动机对交通流进行模拟，具体模拟某一特定车流密度下的（车流密度由用户设定）单、双车道交通流运行状况，并计算平均速度、换道频率、车流密度等参数。(To take advantage of cellular automata to simulate the traffic flow, the specific simulation under a particular density (density is set by the user), the running status of two-lane traffic flow and calculate the average velocity, frequency and density of the lane changing parameters.)

球谐函数的小程序，有必要的参考价值，对于理解有一定的帮助(Legendre function)

求出信号噪声的方差，对干扰信号的噪声的方差进行估测。( EVAR Noise variance estimation. Assuming that the deterministic function Y has additive Gaussian noise, EVAR(Y) returns an estimated variance of this noise.)

该程序用于计算n根平行导线间的串扰,程序结构及说明见程序内。源可以是单频的或脉冲的（这里给出的是频域的）。频率、波形、线长、电源及负载阻抗均可在用MATLAB编写的语句中方便地修改。但必须输入导线系统每单位长度的电感、电容矩阵。(The procedure used to calculate n root of crosstalk between parallel wires, program structure and description of process. Source can be single frequency or pulse (here is given by the frequency domain). Frequency, waveform, the line is long, power and load impedance can be found in the use of MATLAB statements prepared easily modified. However, the system must enter a wire per unit length inductance, capacitance matrix.)
