| Abstract: | The Vertical-BLAST is effective in achieving high data rate in wireless communication.The MMSE detection algorithms can restrain the interference among the information flow and reduce the noise in Rayleigh Slow-Fading Channels.A Symbol by Symbol MMSE-SIC detection algorithm based on its signal model is proposed to enhance the performance of signal error rate(SER) of the systems for Rayleigh Fast-Fading Channels,which combines Multi-variables Statistical Analysis,Successive Interference Cancellation and Opti... |
