Gaussian and Flat Rayleigh Fading Channel Influences on PAPR Distribution in MIMO-OFDM Systems

Résumé

Multiple-input multiple-output orthogonal frequency division multiplexing systems (MIMO-OFDM) has became a promising candidate for high performance 4G broadband wireless communications. However, like OFDM, one main disadvantage of MIMO-OFDM is that the signals transmitted on different antennas may exhibit a prohibitively large peakto- average power ratio (PAPR). In this paper, the influence of gaussian and flat Rayleigh fading channel on the PAPR of MIMO-OFDM passband signals at the receiver-side have been analyzed. A mathematical expression for complementary cumulative distribution function (CCDF) of the PAPR has been derived which depends on the number of transmitting antennas and the parameters of channel.
