    The behavior of orthogonal frequency division multiplexing (OFDM) signals in bandpass nonlinearity is presented. In particular, in-band biterror- rate (BIER) degradation and induced adjacent channel interferences, as a result of amplitude limiting or clipping, are analyzed. In the presence of both nonlinear distortion and additive noise, optimized output power back-off is provided to balance the r... View full abstract»

    Performances of two different channel interpolation methods to be used with Orthogonal Frequency Division Multiplexing (FDM) systems are investigated. The considered scheme uses constant pilot frequencies for channel response estimation. The interpolation techniques are piecewise-constant and piecewise-linear methods which due to their inherent simplicity are straightforward to implement. The resu... View full abstract»

    This paper explains how a windowing of the OFDMSignal in the time domain contributes to its improved reception. The windowing uses the part of the guard interval that is not disturbed by multipath reception. The length of the window adapts to the transmission conditions. This window may be realized with a raised cosine or other kind of function that fulJills the nyquist criterion. An easy way to i... View full abstract»
