La technique d'étalement peut améliorer les performances du système car elle atténue l'influence des canaux de sous-porteuses fortement atténués. Les propositions de mise en œuvre de systèmes de multiplexage par répartition orthogonale de la fréquence (OFDM) incluent l'étalement des symboles de fréquence (FSS) basé sur la transformée de Walsh-Hadamard (WHT) et la transformée de Fourier discrète (DFT). Dans un multiplexage par répartition en fréquence à porteuse unique (SC-FDMA), de bonnes performances sont obtenues grâce à l'attribution de sous-porteuses entrelacées. De plus, dans un système à entrées multiples et sorties multiples (MIMO), l'entrelacement du fonctionnement des différentes antennes d'émission est également efficace. En combinant ces techniques, dans cet article, nous proposons différentes allocations d'antennes entrelacées avec l'étalement WHT/DFT complet et divisé pour une interférométrie de porteuse à haute résolution temporelle (HTRCI) MIMO-OFDM.

Abstract: The spreading technique can improve system performance since it mitigates the influence of deeply faded subcarrier channels. Proposals for implementing orthogonal frequency division multiplexing (OFDM) systems include frequency symbol spreading (FSS) based on the Walsh-Hadamard transform (WHT) and the discrete Fourier transform (DFT). In a single carrier frequency division multiplexing (SC-FDMA), good performance is obtained by the interleaved subcarrier allocation. Moreover, in a multiple-input multiple-output (MIMO), interleaving the operation of the different transmit antennas is also effective. By combining these techniques, in this paper, we propose the different antenna interleaved allocation with the full and divided WHT/DFT spreading for a high time resolution carrier interferometry (HTRCI) MIMO-OFDM.
