Abstract:
(EN) A vehicle-mounted navigation channel adaptive system based on a pre-distorter comprises a microcontroller module, a GPS module, an analog-to-digital conversion module, a power supply module, a pre-filter, a frequency hopping signal processor, an error processor, a time delayer, the pre-distorter, a post-filter, and an antenna. By using an adaptive pre-distortion system, the system compensates vehicle-mounted GPS location positioning, position information collected by a vehicle-mounted terminal can be better transmitted, out-of-band spectrum expansion of a BOC signal can be effectively restrained, out-of-band distortion can be reduced, a constellation diagram is optimized, in-band distortion is reduced, and distortion influences on the BOC signal by the navigation channel can be well eliminated.
(FR) L'invention concerne un système adaptatif de canal de navigation monté sur véhicule basé sur un élément de pré-distorsion, qui comprend un module de microcontrôleur, un module GPS, un module de conversion analogique-numérique, un module d'alimentation électrique, un pré-filtre, un processeur de signal de saut de fréquence, un processeur d'erreur, un retardateur temporel, l'élément de pré-distorsion, un post-filtre, et une antenne. En utilisant un système de pré-distorsion adaptatif, le système compense un positionnement d'emplacement GPS monté sur véhicule, des informations de position collectées par un terminal monté dans le véhicule peuvent être mieux transmises, une expansion de spectre hors-bande d'un signal BOC peut être efficacement contenue, une distorsion hors bande peut être réduite, un diagramme de constellation est optimisé, une distorsion dans la bande est réduite, et des influences de distorsion sur le signal BOC par le canal de navigation peuvent être correctement éliminées.
