Dans cet article, nous proposons une nouvelle méthode pour collecter des informations de détection en utilisant un signal orthogonal à bande étroite pour la détection coopérative en radio cognitive. Il est souhaitable d'améliorer les performances de détection du spectre en s'opposant à l'effet de localité d'un canal sans fil ; la détection coopérative utilisant plusieurs entrées d'informations de détection provenant des nœuds de détection environnants a attiré l'attention. La détection coopérative nécessite que les informations de détection soient collectées au niveau du nœud maître pour déterminer l'existence d'un signal primaire. Si la méthode de collecte d'informations utilisée conduit à des redondances, la capacité totale des réseaux secondaires n'est pas améliorée. Dans cet article, nous proposons une nouvelle méthode de collecte d'informations de détection qui mappe les informations de détection au signal orthogonal à bande étroite afin d'obtenir une collecte simultanée d'informations de détection au niveau du nœud maître. Dans ce procédé, les informations de détection sont mappées sur un signal de sous-porteuse orthogonale d'une structure de multiplexage par répartition orthogonale de la fréquence (OFDM) afin de réduire la ressource de fréquence requise pour la collecte d'informations de détection. Les signaux orthogonaux sont transmis simultanément à partir de plusieurs nœuds de détection. Cet article évalue les performances de la méthode de collecte d'informations proposée et confirme son efficacité.

Abstract: In this paper, we propose a novel method for gathering sensing information by using an orthogonal narrowband signal for cooperative sensing in cognitive radio. It is desirable to improve the spectrum sensing performance by countering the locality effect of a wireless channel; cooperative sensing by using multiple inputs of sensing information from the surrounding sensing nodes has attracted attention. Cooperative sensing requires that sensing information be gathered at the master node for determining the existence of a primary signal. If the used information gathering method leads to redundancies, the total capacity of the secondary networks is not improved. In this paper, we propose a novel method for gathering sensing information that maps the sensing information to the orthogonal narrowband signal to achieve simultaneous sensing information gathering at the master node. In this method, the sensing information is mapped to an orthogonal subcarrier signal of an orthogonal frequency division multiplexing (OFDM) structure to reduce the frequency resource required for sensing information gathering. The orthogonal signals are transmitted simultaneously from multiple sensing nodes. This paper evaluates the performance of the proposed information gathering method and confirms its effectiveness.
