matlab code for EMT field theory project stating mashgrid quiver

说明：  ｗａｖｅ：小波包分解，对信号进行小波包分解，将信号按频率成分分解出来，并且估计小波包能量(wave: wavelet packet decomposition, wavelet packet decomposition of the signal, the signal decomposition by frequency components out, and the estimated wavelet packet energy)

基于matlab的有限差分法程序，计算无限长金属槽的槽内电压(Based on the finite difference method matlab program to calculate the tank voltage infinitely long metal trough)

说明：  搭建了模电电路，实现仿真并得到仿真U I波形(The analog circuit is built, and the simulation UI waveform is obtained)

matlab下利用s-function实现rs232编码、解码及通讯的实例程序。需要在matlab下利用mex编译使用（参见s-function用法）(matlab using s-function to achieve rs232 encoding, decoding and communication procedures of the examples. Need to use matlab using mex compiler (see the use of s-function))

this code first reads an image and decomposed it in discrete wavelet transformation.hl1 and hl2 are extracted to embed watermark. watermark is added to hl1 and lh1 and inverse dwt is applied.

在平稳瑞利多径信道下，用BPSK调制，用matlab 仿真由最大似然译码的性能。(It discuss a receiver structure called Maximum Likelihood (ML) decoding which gives us a better performance. We will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.)
