很好用的有限元法求解偏微分MATLAB编程

CDMA系统仿真,非常好的东西哦，希望大家赶快下载吧(CDMA system simulation)

说明：  用matlab程序模拟实现cdma系统的整个过程。包括并串、串并转换，m序列的产生，直接扩频、解扩，qpsk的调制解调，载波调制解调等。(Matlab simulation procedures used to achieve the whole process of cdma systems. Including and string SERDES, m sequence generation, direct spread spectrum, despreading, qpsk the modulation and demodulation, carrier modulation and demodulation, etc..)

小波变换的关键在于将原始信号分解到哪一层，在哪一层中找到模极大值点(wavelet transform is the key to where the original signal decomposition level, in which one found modulus maximum points)

关于通信系统的simulink仿真，包括基本介绍，数字信号传输，信道编码，OFDM方式，MIMO系统仿真(On the communication system simulink simulation, including a basic introduction to digital signal transmission, channel coding, OFDM mode, MIMO system simulation)

DTMF 系统的matlab实现，发送电话11位电话号码在接收端识别。(DTMF system matlab realize, send telephone 11 telephone numbers identified on the receiving end)

This program alows you to add noise to a source and the remove the noise by filtering.

说明：  微网系统并网和离网两种状态的研究仿真。内容详细，常用控制算法的对比研究与仿真(Micro-grid systems and networks and off-grid simulation study of two states. Detailed, comparative study of commonly used control algorithms and simulation)

采用的是脉冲对消法，IDW距离反比加权方法，分析了该信号的时域、频域、倒谱，循环谱等,通过虚拟阵元进行DOA估计，用于特征降维，特征融合，相关分析等,在matlab R2009b调试通过。
