Abstract

This paper gives a general approximation formula of the largest eigenvalue distribution in correlated MIMO (multiple input multiple output) Rayleigh channels. The proposed formula is given by improvement of SIMO (single input single output) based analysis method of MIMO systems, and applicable to any type of correlation including the case covariance matrix has degenerated eigenvalues for which conventional exact formula could not be used. The effectiveness of the proposed equation for various correlated MIMO channels is demonstrated through computer simulations.
