Abstract
In this paper, a novel band-pass equalizer for orthogonal multiple carrier (omc) data receivers is investigated. Essentially, the band-pass equalizer consists of an fir filter preceding the receiver filter bank and processing the whole transmission band at the high input sampling rate. The coefficients of the fir equalizer are optimized iteratively in the sense of a minimum mean square error of the received and demodulated signals. A simulation of the proposed equalizer on a work-station shows that it adapts in a substantially shorter time compared to adaptive multichannel baseband equalizers at a comparable computational efficiency.
Résumé
Un nouvel égaliseur passe-bande pour récepteur à porteuses multiples orthogonales est étudié. Essentiellement, ľégaliseur passe-bande est un filtre rif qui précède le banc defiltres de réception et traite la totalité de la bande transmise à la fréquence ďéchantillonnage haute. Les coefficients sont optimisés par itération au sens des moindres carrés de ľécart entre les signaux reçus et démodulés. Une simulation montre que cet égaliseur converge plus rapidement que les égaliseurs adaptatifs multicanaux en bande de base, à complexité comparable.
