本文提出了一种节点密度和剩余能量传感器网络加权分群算法，该分群算法优化了群首 选择，均衡了网络节点的能量消耗，延长了网络的生命周期(This paper proposes a residual energy of sensor nodes in the network density and weighted clustering algorithm, the clustering algorithm to optimize the group' s first choice, balancing the energy consumption of network nodes to extend the network life cycle)

The above matlab code include the simulation of dipole antenna and current distribution using standard algorithm

This file is the programs of (chapter 2) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related to shadowing effects. It helps you to simulate wireless shadowing effects.

π／4DQPSK抗噪声性能仿真与分析,基于扩频和CDMA系统(π/4DQPSK anti-noise performance simulation and analysis, based on spread spectrum and CDMA systems)

数值计算中的特征值、特征向量计算，采用matlab代码(eigenvalue computation)

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)

Exercise on kalman filter with model AR, ARMA, ecc.
