In the case of multi-input multi-output MIMO frequency selective channel the solution requires the derivation of the eigenvalue decomposition of the MIMO frequency response which, for every frequency bin, have generalized Wishart distribution. This paper shows the methodology used to derive the statistics of eigenvalues and eigenvectors and applies this methodology to the derivation of the average channel Capacity and of its characteristic function. The bound on the outage Capacity is then obtained using the characteristic function. Simple expressions are derived for the case of uncorrelated Rayleigh fading and for an arbitrary finite number of transmit and receive antennas.
