Abstract

Abstract

MIMO is a main capacity improving technique in wireless communication. In slowly fading channel MIMO receiver can feedback the Channel State Information (CSI) to transmitter for the purpose of improving system performance. Traditional feedback-precoding scheme Singular Value Decomposition (SVD) affected by spatial correlation and requirement of traditional VBLAST system about number of transmission and receive antennas, its application is severely restricted. This paper presents an adaptive MIMO transmission system, adopting uniform channel parameter feedback mode and Space-Time Block Code (STBC), this technique can overcome the drawbacks of SVD scheme mentioned above. The simulation results show this kind of system can work with receive antennas less than transmission antennas and perform well under high correlated channel.
