摘要：
A simple MIMO-OFDM wireless communication system is constructed based on the analysis of the technical principles and the system models of the MIMO technology and the OFDM technology. The system combines the MIMO system and the OFDM system together, space-time coding is done in the transmitter firstly, the signal is launched after OFDM modulated, and the process of the receiver is the inverse process of the transmitter. The system performance is simulated by using the software MATLAB, the experimental result shows that the MIMO-OFDM wireless communication system has better performance when the antenna number is very large and the other conditions are identical, but the system performance will reduce if the carrier number increases.
