Bandpass filter simulation analog communication

matlab解决TPS问题，简单易懂，已运行测试(matlab solve TPS, easy to understand, and has been running test)

这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模块，并统括系统性能的仿真验证了系统设计的可靠性。 (This is a relatively complete simulation of OFDM communication system design, including coding, modulation, IFFT, the upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, a variety of synchronization, demodulation and decoding module, and system performance omnibus simulation of the system reliability.)

this is a source code of beamforming

采用matlab语言，但不是采用其神经网络工具箱开发的BP人工神经网络程序，原始底层代码，对于想利用其它语言开发商业软件的网友可先学习本代码，然后可方便转写。(Using matlab language, but not using its neural network toolbox developed by BP artificial neural network program, the original low-level code, use of other languages who want to develop commercial software, users can first learn the code, and then can be easily transferred to write.)

DSP windowing function

computes the shortening-signal-to-noise ratio in dB,tail energy in dB and the effective channel impulse response(computes the shortening- signal-to-nois e ratio in dB. tail energy in dB and the effective channel impu lse response)

两种亚像素级角点检测方法。一种曲面拟合，一种灰度梯度。并可输出坐标，精度较高，main为运行程序。(The two sub-pixels corner detection method. A surface fitting, a gray gradient. And output coordinates, accuracy, main to run the program.)

这是关于数字预失真的仿真程序，应用LMS急降方法实现系数更新，对失真有很好的效果(This is the digital predistortion simulation program, the drop of the LMS coefficient update method implementation, have a good effect on the distortion)

中间包括好几个希尔伯特黄的算法，基于MATLAB软件下运行。有emd-visu,emd-separation,emd-sampling,emd-n,里面还有hht 其他的内容，完整，经过测试。做信息处理，Fourier 是个万金油。HHT的优势所在，HHT是一个超adaptive的方法。
