Abstract
The effects of Rayleigh fading on a wireless communications
link and MIMO technique to combat fading is explored
in this paper. In harnessing spatial diversity, the use of Quasi-
Orthogonal space-time block code (QO-STBC) is proposed to
combat fading. QO-STBC codes are able to achieve a unity
rate with more than two antennas. The concept of constellation
rotation for QO codes to maximize the available diversity is
demonstrated. QO codes are shown by simulation to be able
to achieve full diversity, despite the fact that the codes are nonorthogonal.
