Abstract

MIMO technology can greatly increase system capacity, improve system bandwidth utilization and improve system performance without increasing system bandwidth and transmission power, thus becoming the key technology of a new generation of high data rate, multi-data type wireless communication systems. The MIMO system is studied in this paper, mainly focusing on the channel capacity analysis of MIMO system. First, starting from the concept of MIMO, the current wireless communication technology is introduced. Then, the basic principle of MIMO technology, space-time coding technology and the model and capacity of MIMO system are introduced. Finally, the capacity of MIMO system with the same transmitting antenna, different receiving antennas and different SNR is simulated by MATLAB software, and the simulation results are analyzed.
