BER of OFDM with diversity and pulse shaping in Rayleigh fading environments

This paper derives the bit error rate (BER) of Orthogonal Frequency Division Multiplexing (OFDM) systems with pulse shaping for ICI reduction employing Lth-order maximal ratio combining (MRC) diversity in Rayleigh fading environments. The probability density function of the signal-to-interference ratio per bit γ in the presence of the total average inter-carrier interference (ICI) power PICI is also derived. Simulation results are given and discussed.
