Cet article étudie les performances de la diversité de transmission à commutation de temps (TSTD) de liaison descendante assistée par ARQ dans le système WCDMA Low Chip Rate (LCR)-Time Division Duplex (TDD), lorsque la commutation d'antenne et la rampe de puissance sont appliquées. À l'aide du signal ARQ, où le récepteur envoie l'accusé de réception (ACK ou NACK) à l'émetteur, le schéma TSTD proposé commute l'antenne d'émission et augmente la puissance d'émission pour les données retransmises, lorsque l'émetteur reçoit un signal NACK. Les résultats de simulation démontrent que lorsque la vitesse du mobile est de 3 km/h et qu'un taux d'erreur de trame (FER) est fixé à 1 %, le schéma de commutation d'antenne produit un gain de performance de 2 à 3 dB en termes d'Eb/N0 moyen, et le la rampe de puissance donne un gain de 0.7 dB à 1.6 dB, par rapport au TSTD conventionnel assisté par ARQ. De plus, 6% de gain de débit est obtenu en amalgamant la commutation des antennes ainsi que la rampe de puissance, lorsque la moyenne Eb/N0 est égale à 0 dB.

Abstract: This paper investigates the performance of ARQ-aided downlink Time Switched Transmit Diversity (TSTD) in the WCDMA Low Chip Rate (LCR)-Time Division Duplex (TDD) system, when antenna switching and power ramping are applied. With the help of the ARQ signal, where the receiver sends the acknowledgement (ACK or NACK) to the transmitter, the proposed TSTD scheme switches the transmit antenna and ramps up the transmission power for the retransmitted data, when the transmitter receives a NACK signal. Simulation results demonstrate, that when the mobile speed is 3 km/h and a frame error rate (FER) is set to 1%, the antenna switching scheme yields 2 dB to 3 dB performance gain in terms of average Eb/N0, and the power ramping gives 0.7 dB to 1.6 dB gain, compared with the conventional ARQ-aided TSTD. In addition, 6% of throughput gain is shown by amalgamating the antennas switching as well as the power ramping, when the average Eb/N0 is equal to 0 dB.
