The optimization of ergodic channel capacity is investigated for multiple-input multiple-output (MIMO) multiple antenna systems with co-channel interference when the covariance feedback is available at the transmitter. An equivalent form of the co-interference component is first derived. Then an optimal capacity estimation algorithm is proposed by performing gradient projection algorithm which is based on nonlinear programming theory. Finally, Monte-Carlo simulation is given. The numerical results show that the performance with the proposed algorithm is close to the optimal one which is obtained by water-filling algorithm when both the interference power and the correlation between antennas are strong.
