We study the performance limits of a radio system consisting of a transmitter with t antennas and a receiver with r antennas over a fading additive white Gaussian noise channel.We derive the opti al coding scheme minimizing the information outage probability and alyze its performance in terms of outage bility and delay-limited capacity.We show that, asymptotically, the delay-limited capacity grows linearly with m , min(t,r )and is almost independent of the number of fading blocks M which implies the existence of a trade-off between spatial (multiple antennas)and time diversity (interleaving).
