Abstract

The effect of imperfect channel information on the performance of orthogonal space-time block codes is considered in this paper. The symbol error rate of the M-QAM constellation of an orthogonal space-time block code is derived taking into account the effect of imperfect channel information in a Rayleigh fading channel. Derived results show that imperfect channel information destroys the orthogonality of OSTBC, resulting in a error floor that increases with the channel estimation error and the normalized doppler frequency.
