Abstract :
Based on the analysis of the technical principles and the system model of the MIMO and OFDM technologies, a simple MIMO-OFDM wireless communication system is constructed. The system is composed of transmitter, channel, receiver, and so on. Space-time coding is done in the transmitter, the signal is launched after OFDM modulation, and the process of the receiver is the inverse process of the transmitter. The system performance is simulated by using the software Matlab, the experiment result shows that the MIMO-OFDM wireless communication system has better performance when there are more antennas. But, with the increase of the carrier number, the system performance will reduce because of the interference between sub-carriers.
