Abstract :
We study the relative impact of rate and raw diversity order on the capacity and performance of linear space-time codes. Outage capacity is not directly affected by raw diversity order, but it is strongly impacted by the rate of a space-time code. Specifically, if a linear space-time code operating over a t-input, r-output Rayleigh-fading channel has rate R\n\n\t\t
