程序对4发4收系统进行V-BLAST检测算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端分别采用ZF、MMSE、ZF-OSIC、MMSE-OSIC四种检测算法，根据其误比特率比较性能。(V-BLAST detection algorithm simulation program 4 of 4 admission system. Send signals using QPSK modulation, channel quasi-static Rayleigh flat fading channel, the introduction of noise with mean zero Gaussian white noise receiving end, respectively, ZF, MMSE, ZF-OSIC, MMSE-OSIC four detection algorithm based on its The bit error rate of the comparative performance.)

Face Recognition Based on Overlapping DCT

this is the code for DCT color image compression. You can check the compression quality by checking your output image which will be stored in current folder.
