Description: 由matlab编写,带GUI界面。对bmp文件进行Vector Quantization。运行其中的VQ_GUI.m文件。 程序肯定是调试无误的。虽然比较耗时,但是最后能达到较好的图像效果和SNR。毕竟相比于VC,matlab运行较慢。 注意在点open打开了一个bmp文件过后,一定要先点VQ code,进行其他操作才能有效。-prepared by Matlab, with GUI interface. Bmp files to Vector Quantization. VQ_GUI.m running the paper. Debugging procedure is certainly unmistakable. Although it is quite time-consuming, but in the end will get better images and SNR. After all, compared to the VC, Matlab run slower. Attention to the point of open open after a bmp file, you must first point VQ code, other operations to be effective.

Description: In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.-In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model.
