Abstract

Dans un système de communication sans fil, un appareil de communication placé à une extrémité d'émission comprend une unité de génération de signal de référence qui générant, en tant que symboles de référence devant être transmis conjointement avec les données transmises, une séquence de symboles de référence sur la base d'une séquence de pseudos bruits. Un appareil de communication placé à une extrémité de réception peut utiliser la séquence de symboles de référence générés par l'unité de génération de signal de référence pour déterminer un état de réception de signal avec suppression ou réduction de l'interférence avec le signal de référence.
