2D FDTD realization with Near-to-Far field transformation

说明：  OFDM系统发射部分matlab仿真源代码(OFDM system simulation matlab source code transmitter)

Make the Huffman-tree from the lengths of the Huffman codes. The Huffman codes are also needed, and if they are known, they can be given as an extra input argument.

该文件是包括正弦信号通过加性噪声信道的时域输入波形和输出波形图(The file includes a sinusoidal signal by the time domain input and output waveforms of the additive noise channel)

对水印图像进行置乱，然后嵌入到载体图像小波域中的细节子带中(the watermark image is Scrambled, and then embedded into the details of wavelet sub-band domain)

有关波束形成的指向性问题的波束图及相关代码 (The beamforming point the beam pattern and associated code)

最小生成树，不只到谁能将他转换成MATLAB语言的算法？(Minimum spanning tree, not only to him who can convert MATLAB algorithms language?)

这是一套完整的求解连铸二冷区喷嘴模拟试验传热系数的程序(This is a complete solution Caster two district cooling nozzle heat transfer coefficient simulation test procedures)

使用matlab中快速傅里叶变换fft实现滤波(The use of the MATLAB FFT FFT filter)

小波包去噪，用小波包去除一维信号的噪声,分解小波包系数画图说明比较全面(Wavelet Packet Denoising using wavelet packet to remove the noise of a one-dimensional signal decomposition wavelet packet coefficients drawing the more comprehensive)
