Major Factors Affecting MIMO Channel Capacity

In order to research the channel capacity of multiple-antenna systems, multiple input multiple output (MIMO) channel capacity formula is studied based on the information theory. By building the model of MIMO system, the paper analyzes the channel capacity of MIMO system under frequency-selectivity fading channel. Our analysis and discussion are focused on the effects of antennas, the channel correlation, and Rician K-factor which influence the MIMO capacity. The results proposed are validated by computer emulator.
