Volterra NLMS

function S = steeringv(M,x) define steering vector free space wavelength of 15cm at resonant freq of 2GHz lamda = 0.15 d = lamda/2 inter-element spacing K = 1:M x is DOA of the received signal S = exp((-2*pi*j*(K-1)*d*sin(x))/lamda)

Generate Bpsk modulation using Monte Carlo simulation.

matlab基础与提高，非常好的一门教程(matlab basic and enhance, a very good tutorial)

sd dac 的matlab设计工具。里面有详细的介绍(SDtool box)

看了一段时间的3GPP的信道建模，所以自己动手写了一个（参考了该协会的标准代码，不过改良了一些，执行效率更高）(the 3GPP SCM model building. Comparing to the original code, this task is more efficient and clearer.)

说明：  MonteCarlo抽样Matlab程序(Sampling from a discrete distribution)

对于球形颗粒物，r为球的半径但非球形颗粒物，r还不确定。 水中由悬浮颗粒物产生的光散射引起光子的传输方向发生变化，光子已偏离了准直方向。但不会改变光子的其他特性随机过程。 (scattering light transmission in water )

dtmf的matlab实现.包含理论分析.适合初学者.(DTMF to achieve the matlab. contains theoretical analysis. suitable for beginners.)

说明：  荣格库塔法解微分方程组，比matlab自带的ode求解命令更准确，误差更少(Rong-Kutta method for solving differential equations group' s ode to solve than the matlab command comes more accurate, less error)

Bessel低通滤波器特性幅频及相频特性分析及其阶跃响应和方波响应(Bessel low-pass filter characteristics of amplitude and phase frequency characteristics of frequency and step response and the square wave response)
