Zero padding (ZP) of multicarrier transmissions has been proposed as an appealing alternative to the traditional cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) to ensure symbol recovery regardless of the channel zero locations.

We extend the turbo demodulation procedure proposed by Li and Ritcey (see IEEE Journal on Selected Areas in Communications, vol.17, no.4, p.715-24, 1999) and by Magniez, Muquet, Duhamel, Buzenac and de Courville (see Proc. Int. Symp. on Turbo Codes a

This paper proposes a new blind channel estimation method for orthogonal frequency division multiplexing (OFDM) systems. The algorithm makes use of the redundancy introduced by the cyclic prefix to identify the channel based on a subspace approach. T

Space time coding has by now been well documented as an attractive means of achieving high data rate transmissions with diversity and coding gains, provided that the underlying propagation channels can be accounted for. We rely on redundant linear pr

We provide a geometrical interpretation of the iterative decoding of bit interleaved coded modulation (BICM) as an algorithm performing successive projections of probabilities densities onto well defined density spaces with respect to the Kullback di

A new subspace method performing the blind and semi-blind identification of the transmission channel suited to multicarrier systems with cyclic prefix (OFDM) is proposed in this paper. This technique has the advantage to preserve the classical OFDM e

Turbo-equalization has been proposed as a powerful means for recovering unknown symbols sent through frequency selective channels. Most algorithms proposed so far were designed in the framework of a binary symbol alphabet, and then extended to modula

The effects of uniform spreading in OFDM-CDMA systems is the harmonization at the reception of the signal to noise ratio between the sub-bands which prevents the good performance of successive decoding algorithms. This paper proposes a new hybrid spr
