  • Abstract
    We analyze optimum (space-time) adaptive power transmission policies for Rayleigh fading MIMO channels when CSIT and CSIR are available. We show that our power allocation policy provides exponential diversity gain2 (BER≤αe-f(n(t),n(r)) where α>0 is a constant, and f>0 is an increasing function of nt&nr) if perfect CSIT is available. Exponential diversity is lost at high SNR if the quality of CSIT degrades.
