Application and Performance of Space Time Coding in MIMO System—Analysis of Alamouti Space Time Coding Scheme
: This research first intuitively shows the implementation diagram of a MIMO system, and then introduces transmission diversity and space-time coding technology, with space-time coding technology belonging to the category of spatial diversity technology. The earliest and most classical Alamouti space-time coding scheme is then applied to MIMO wireless communication systems. The principle of the Alamouti space-time coding scheme is demonstrated, and a theoretical demonstration is carried out in a MIMO diversity system with two transmitters and one receiver. Finally, the Alamouti space-time coding scheme is simulated using MATLAB, and it is verified that the diversity gain and coding gain are obtained by using the Alamouti space-time coding scheme in the MIMO system.
