说明：  解两点边值问题的有限元程序代码（matlab）(Solution of Boundary Value Problems of Finite Element code (matlab))

Matlab版俄罗斯方块，个人一直认为，这个游戏或者说这个程序很经典！ 如果你能掌握这个程序，你对Matlab的外功已经不成问题，回家修炼一下内功，就能毕业了！！ 不说别的，先来玩玩，别忘了把音箱打开！感受儿时的乐趣 程序作者：Pascal Getreuer (Matlab version of Tetris, individuals have always thought that this game or that the program was classic! If you can master this program, you have no problem Matlab' s external work, home practice about internal strength, we can graduate! ! If nothing else, the first to play, do not forget to turn on speakers! Experience the fun process of childhood: Pascal Getreuer)

说明：  在matlab中实现信号的模数以及数模转换，并包含简单的界面(achieve the Matlab Signal Module and hundreds of analog conversion, and includes a simple interface)

this code descibe matlab code for quadtree decomposition in fractal image compression

发送装置：随机信号产生、脉冲成型（上采样可调，滚降可调）； 发送：AWGN信道（信噪比范围可调） 接收设备：QPSK调制解调 ，匹配滤波，判决 画出接收信号的眼图、星座图；计算误码率并与理论值比较。 (Transmitting device: random signal generator, pulse shaping (the sampling adjustable, adjustable roll-off) Send: AWGN channel (SNR range is adjustable) Receiving equipment: QPSK modulation and demodulation, matched filtering, judgment   BER is calculated and compared with the theoretical value draw the received signal eye diagram, constellation.)

通过引入7种加权函数实现信号中的时延估计，为广义互相关法(By introducing seven kinds of weighting functions for signal delay estimation, generalized correlation method)

最小均方误差（MMSE）的算法，MIMO OFDM matlab仿真,ICA（主分量分析）算法和程序。( Minimum mean square error (MMSE) algorithm, MIMO OFDM matlab simulation, ICA (Principal Component Analysis) algorithm and procedures.)

三维声波正演模拟的matlab程序 边界条件为pml( Three dimensional acoustic wave forward simulation of matlab program)
