Abstract

In this paper, we study the capacity of space time block codes (STBCs) over correlated Rayleigh flat-fading MIMO channels combined with adaptive transmitting techniques. We study three adaptive schemes known as optimal power and rate allocation (opra), optimal rate allocation (ora), total channel inversion with fixed rate policy (cifr) and its truncated variant (tifr). We obtain closed form capacity expressions of STBCs combined with these adaptive schemes, taking into account the effect of channel correlation, hence avoiding numerical integrations or Monte-Carlo simulations
