MIMO technology refers to the use of multiple transmitting antennas and multiple receiving antennas to improve the quality of information transmission. MIMO technology includes space-time coding, channel modeling, channel estimation, and other technologies. This paper mainly studies the space-time coding technology and precoding technology in the MIMO system through Matlab. First, the Alamouti coding is extended to the MIMO system with more transmitting and receiving antennas. This way can get a space-time block code. Finally, this paper will introduce the precoding technology and compare it with simulation analysis by simulating and analyzing its bit error performance.
