L'accès dynamique au spectre (DSA) exploite les ressources de fréquences vacantes via un accès sans fil distribué. Les deux nœuds du DSA, maître et esclave, accèdent à des canaux différents et ne peuvent donc pas communiquer entre eux. Pour compenser l'inadéquation des canaux d'accès entre les deux nœuds, un canal de rendez-vous, qui échange des signaux de contrôle entre deux nœuds, a été envisagé. Le canal de rendez-vous basé sur le rapport d'occupation de canal (COR) construit le canal de manière adaptative en fonction de l'occupation du canal d'autres systèmes, et un canal de rendez-vous à grande vitesse ainsi qu'une efficacité d'utilisation élevée de la ressource de fréquence sont obtenus grâce à l'exploitation du canal de rendez-vous vacant. canal. Dans le canal de rendez-vous basé sur COR, le maître et l'esclave reconnaissent le canal avec un COR mesuré minimum comme canal supérieur. Comme le maître envoie les signaux de commande via le canal supérieur reconnu par le maître, l'esclave accède au canal supérieur reconnu par l'esclave avec un débit d'accès plus élevé qu'aux autres canaux. En conséquence, l'esclave peut recevoir les signaux de commande avec une forte probabilité et ainsi obtenir un canal de rendez-vous à grande vitesse. Si le maître et l'esclave reconnaissent l'autre canal comme canal supérieur, le débit d'accès à l'autre canal devrait être plus élevé. En effet, l'esclave a la possibilité de recevoir les signaux de commande via un canal différent du canal supérieur reconnu par l'esclave et la probabilité élevée que l'esclave puisse recevoir les signaux de commande est ainsi maintenue. Par conséquent, le taux d'accès de l'esclave doit être construit conformément à la reconnaissance du canal supérieur par le maître et l'esclave. Dans cet article, le taux d'accès de l'esclave au canal supérieur est construit de manière optimale en utilisant la probabilité analysée d'achèvement du canal de rendez-vous. L'analyse de la probabilité d'achèvement du canal de rendez-vous comprend la reconnaissance du canal supérieur par le maître et l'esclave. Même si le maître et l'esclave reconnaissent le canal différent, le taux d'accès construit de l'esclave peut maintenir le canal de rendez-vous à grande vitesse. D'après l'analyse théorique et la simulation informatique, le canal de rendez-vous basé sur COR avec le taux d'accès optimal au canal avec le COR le plus bas permet d'obtenir un temps réduit pour le canal de rendez-vous.

Abstract: Dynamic spectrum access (DSA) exploits vacant frequency resources via distributed wireless access. The two nodes of DSA, master and slave, access different channels, and thus, cannot communicate with each other. To compensate for the access channel mismatch between the two nodes, a rendezvous channel, which exchanges control signals between two nodes, has been considered. The rendezvous channel based on channel-occupancy ratio (COR) adaptively constructs the channel in accordance with the channel occupancy of other systems, and both a high-speed rendezvous channel and high usage efficiency of the frequency resource are accomplished owing to exploitation of the vacant channel. In the rendezvous channel based on COR, the master and slave recognize the channel with minimum measured COR as the superior channel. As the master sends the control signals through the superior channel recognized by the master, the slave accesses to the superior channel recognized by the slave with higher access rate than to the other channels. As a result, the slave can receive the control signals with highly probability and thus high speed rendezvous channel is achieved. If the master and the slave recognize the different channel as the superior channel, the access rate to the other channel should be larger. This is because the slave obtains the opportunity of receiving the control signals through the different channel from the superior channel recognized by slave and thus the high probability that the slave can receive the control signals is maintained. Therefore, the access rate of slave should be constructed in accordance with the recognition of superior channel by master and slave. In this paper, the access rate of slave to the superior channel is optimally constructed using the analyzed probability of completion of rendezvous channel. The analysis of the probability of completion of rendezvous channel includes the recognition of superior channel by master and slave. Even if the master and the slave recognize the different channel, the constructed access rate of slave can maintain the high speed rendezvous channel. From the theoretical analysis and computer simulation, the rendezvous channel based on COR with the optimal access rate to the channel with the lowest COR achieves reduced time for the rendezvous channel.
