Cet article étudie l'influence du nombre d'antennes, de la différence d'angle entre la direction d'arrivée (DOA) du signal souhaité et celle des signaux brouilleurs, et de la disposition des antennes sur les performances du BER du réseau d'antennes adaptatives cohérentes en diversité (CAAAD). récepteur dans la liaison inverse large bande DS-CDMA (W-CDMA). Des expériences supposant des utilisateurs brouilleurs à haut débit ont été menées dans une salle radio anéchoïque en utilisant une antenne à trois secteurs avec un faisceau de 120 degrés (le nombre maximum d'antennes était de six). Les résultats expérimentaux ont montré que le degré de suppression des interférences provenant des utilisateurs à haut débit du récepteur CAAAD était considérablement augmenté en augmentant le nombre d'antennes, en particulier lorsque le nombre d'utilisateurs brouilleurs était supérieur au degré de liberté du CAAAD. Il a également été vérifié que, même si les performances BER du récepteur CAAAD se sont considérablement améliorées par rapport à une antenne à secteur unique, l'amélioration a remarquablement diminué lorsque la différence DOA entre le signal souhaité et les signaux brouilleurs était d'environ

Abstract: This paper investigates the influence of the number of antennas, the angle difference between the direction of arrival (DOA) of the desired signal and those of interfering signals, and the antenna arrangement on the BER performance of the coherent adaptive antenna array diversity (CAAAD) receiver in the wideband DS-CDMA (W-CDMA) reverse link. Experiments assuming high-rate interfering users were conducted in a radio anechoic room using a three-sectored antenna with a 120-degree beam (maximum number of antennas was six). The experimental results showed that the degree to which the interference was suppressed from high-rate users of the CAAAD receiver was significantly increased by increasing the number of antennas, especially when the number of interfering users was larger than degree of freedom of the CAAAD. It was also verified that although the BER performance of the CAAAD receiver significantly improved compared to a single sectored antenna, the improvement remarkably decreased when the DOA difference between the desired signal and interfering signals was within approximately
