| Abstract: | This paper studies the wireless MIMO system and the effect of antenna correlation on the performance of system capacity.First,the MIMO system model with antenna correlation is introduced,the correlation parameter is given and the expression of correlate channel capacity is deducted.Second,by using Monte Carlo method,we simulate the relationship of channel capacity and antenna angle expansions under the condition of the Gaussian distribution and uniform distribution respectively.It provides a reference for the design of MIMO system with effect of correlation. |
