Le contrôle de la puissance de transmission (TPC) est un aspect important de la transmission sous-jacente dans les réseaux de radio cognitive (CR), car il est capable d'éviter les interférences supplémentaires provenant de la transmission secondaire qui peuvent permettre à l'utilisateur du CR de coexister avec les systèmes primaires environnants. Cependant, en raison de la couverture différente du signal primaire et du signal CR, combinée à la complexité de la communication sans fil, l'émetteur CR à balayage peut ne pas détecter l'existence des systèmes primaires. Cela entraînerait un TPC inexact qui perturberait gravement le service principal. Dans cette lettre, nous proposons un schéma de contrôle de puissance coordonné par le voisin dynamique qui peut éviter la détection erronée du signal primaire et fournir une estimation de distance relativement précise liée au TPC. Les résultats de la simulation montrent que le schéma proposé réduit considérablement les interférences sur les systèmes primaires tout en améliorant le débit global du réseau CR.

Abstract: Transmission power control (TPC) is an important aspects of underlay transmission in the cognitive radio (CR) networks since it is able to avoid the extra interference from secondary transmission which can let the CR user coexist with the primary systems around. However, due to the different coverage of the primary signal and CR signal, combined with the complexity of the wireless communication, the scanning CR transmitter may not detect the existence of the primary systems. It will cause inaccurate TPC which will severely disrupt the primary service. In this letter, we propose a dynamic neighbor coordinated power control scheme that can avoid the misdetection of the primary signal and provide relatively accurate TPC related distance estimation. Simulation results show that the proposed scheme greatly reduces interference to the primary systems while enhancing overall CR network throughput.
