Closed form capacity expressions for space time block codes over fading channels

The Shannon capacity of orthogonal space-time block codes (STBC) is considered for Rayleigh, Ricean and Nakagami-m uncorrelated fading channels and correlated Rayleigh fading channels. In this paper, STBC capacity expressions are derived for several fading channels. The Shannon capacity of a multiple antenna wireless system over a fading channel with continuous-valued inputs and continuous-valued outputs can be obtained.
