Abstract: The combination of MIMO and OFDM is the core technique of B3G and 4G wideband wireless communication, which can effectively increase spectral utilization. Traditionally, design of communication system is simulated with Matlab. This paper realizes the simulation of 4*4 MIMO OFDM wireless communication system using SystemC. Research result demonstrates that MIMO OFDM system provides higher data rate and better performance, and SystemC is a fast operated and easy realized development platform which can save more PC resources.
