Auckland, New Zealand: 2008 International Symposium on Information Theory and its Applications (ISITA2008), 7-10 Dec 2009.http://hdl.handle.net/10092/3365In this paper we consider the level crossing rates (LCRs) of bit error rates (BERs) across the frequency bins of a multiple-input multiple-output (MIMO) system with orthogonal frequency division multiplexing (OFDM) operating over frequency selective Rayleigh fading environments. In particular, we consider each eigenmode as a random process in the frequency domain and compute the LCR for the BER of transmission down the eigenchannels of the MIMO OFDM channel. Many extensions to this work are possible including LCRs in time as well as in frequency. The accuracy of the analytical approximations are verified by Monte Carlo simulations.enMIMO communicationMonte Carlo methodsOFDM modulationerror statisticsConference Contributions - PublishedFields of Research::290000 Engineering and Technology::291700 Communications Technologies::291710 Radio communications and broadcasting not elsewhere classifiedhttps://doi.org/10.1109/ISITA.2008.4895403
