Abstract :
In this paper, the correlated multiple-input multiple-output (MIMO) channel capacity is studied by using the eigenvalue densities of complex central Wishart matrices. These densities are represented by complex hypergeometric functions of matrix arguments, which can be expressed in terms of complex zonal polynomials. We derive a close form ergodic capacity formula for correlated MIMO channels. It is shown how the channel correlation degrades the capacity of the communication system.
