Abstract :
This paper derives a closed-form expression for the capacity of the point-to-point static Gaussian MIMO channel under per-antenna power constraints when the channel matrix is full column rank and the optimal input covariance matrix is full rank. Analytical and numerical examples are given to illustrate the applicability of the result.
