Abstract:

In this paper, we assess the impact of real-world propagation conditions on the maximum achievable diversity performance of communication over MIMO channels. This is done by studying the outage behavior of the single-input single-output (SISO) channel induced by the use of orthogonal space-time block codes (OSTBCs). For Ricean fading MIMO channels we demonstrate the existence of an SNR-dependent critical rate, Rcrit, below which signaling with zero outage is possible and hence the fading channel behaves like an AWGN channel. For SISO channels, Rcrit is always zero. In the MIMO case, Rcrit is a simple function of the angle between the vectorized Ricean component of the channel and the subspace spanned by the vectorized Rayleigh fading component
