Multiple input multiple output (MIMO) communication architecture has spectral efficiencies far beyond those offered by conventional techniques, and is greatly to increase the channel capacity. In this paper, we investigate the MIMO channel capacity in correlated channels using the uniform angular distribution, numerical simulations are performed with Matlab to verify the proposed formula. We prove that, for this model, increase in correlation is equivalent to decrease in signal-to-noise ratio (SNR), the radius of the circular receive antenna array and angle spread are the dominating factors for the channel capacity.
