In orthogonal frequency division multiplexing (OFDM) systems, the subcarriers are generated by an inverse discrete Fourier transform (DFT). OFDM has a relatively slow spectral rolloff. In the literature, the spectra of these subcarriers are often represented by a sequence of sinc functions with the same polarity. This does not explain the intercarrier… (More)

The probability hypothesis density (PHD) filter is a practical alternative to the optimal Bayesian multi-target filter based on random finite sets. It propagates the PHD function, the first order moment of the posterior multi-target density, from which the number of targets as well as their individual states can be extracted. Furthermore, the sequential… (More)

Polynomial cancellation coded orthogonal frequency division multiplexing with overlapping symbol periods (Overlap PCC-OFDM) is a modulation technique that is less sensitive to frequency errors and more robust against multipath distortion than OFDM. A cyclic prefix is no longer needed. However, fading is still a problem and will cause bit errors. Error… (More)

A technique that uses clipping has been recently proposed to reduce the peak-toaverage-power ratio (PAPR) in orthogonal frequency divisional multiplexing (OFDM) signals. The technique uses a discrete Fourier transform (DFT) based filter to reduce out-ofband (OOB) power after the interpolated baseband OFDM signal is clipped. In this paper, the technique is… (More)

In the last years wireless communications have experienced a fast growth due to the high mobility that they allow. However, wireless channels have some disadvantages, like multi-path fading, that make them difficult to deal with. A modulation that efficiently deals with selective fading channels is OFDM. An important disadvantage of OFDM systems is their… (More)
