bpsk调制信号通过rayleigh信道的误码率测量(ber of bpsk over rayleigh channel)

this file content simple example about modulation bit stream.the type of modulation is (FSK,PSK and ask) after modulation data send and received after that show the relationship between signal to noise ratio (snr) and the bit error rate (ber).....

This MATLAB exercise designs and implements a pitch period detector based on detecting and tracking peaks in the autocorrelation of the LPC error signal during regions of voiced speech. The pitch detection procedure is called the SIFT (Simple Inverse Filtering Tracking) method. The SIFT pitch period detector uses a secondary autocorrelation peak in order to detect and correct pitch period detection errors due to effects such as pitch period doubling and related phenomena.

利用声线法对有限空间声场仿真，并对XY平面声压进行渲染(Line method using acoustic sound field simulation of the limited space, and the XY plane render sound pressure)

经典《matlab及其在理工课程中的应用指南》电子书(Classic " matlab and its courses in the sciences and the application of Guide" e-books)

说明：  一个可以实现图像的高频提升MATLAB程序

matlab学习的很好的资料，上传给大家，供大家使用，是ppt的形式，有类型题(matlab reference)

自己写的关于语音分帧，加窗，去噪，端点检测方面的程序，可成功调试 (Write about the voice sub-frame, adding windows, noise reduction, endpoint detection of the procedures, can be successfully debug)

说明：  对图像进行处理后常需要计算图像的PSNR值和NC值(calculate the PSNR and NC of pictures)

说明：  微电网下逆变器pi环控制，可以仿真出结果，波形完整(Micro grid inverter PI ring under control, you can copy the micro grid inverter under PI loop control, can the simulation results, the waveform complete real results, waveform is complete)
