Abstract

Multiple input and multiple output (MIMO) OFDM exploit spatial diversity to improve spectral efficiency. In this paper, we have derived an analytical model for signal to noise plus interference ratio incorporating inter carrier interference (ICI) and average probability of error in MIMO-OFDM using space frequency block code (SFBC) over Nakagami-m fading channel. Results show that average probability of error performance of MIMO-OFDM system in Nakagani fading channel decreases if fading parameter m is increased. At a constant fading parameter m, normalized frequency offset increases as the average probability of error increases.
