Dans les systèmes de partage de spectre dans lesquels l'utilisateur secondaire (SU) accède de manière opportuniste au canal sous licence de l'utilisateur principal (PU), la SU devrait satisfaire à la fois à la contrainte de puissance d'émission de l'émetteur SU et à la contrainte de puissance reçue au niveau du récepteur PU. Cette lettre étudie la capacité ergodique des systèmes de partage de spectre dans les canaux à évanouissement. L'expression de la capacité ergodique ainsi que le schéma d'allocation de puissance optimal sont dérivés en tenant compte à la fois des contraintes de puissance moyenne d'émission et de réception. La fonction de capacité en termes de deux contraintes de puissance se révèle être divisée en région limitée en puissance d'émission, région limitée en puissance reçue et région limitée en double. Des résultats numériques dans les canaux d'évanouissement de Rayleigh sont présentés pour vérifier notre analyse.

Abstract: In spectrum-sharing systems where the secondary user (SU) opportunistically accesses the primary user (PU)'s licensed channel, the SU should satisfy both the transmit power constraint of the SU transmitter and the received power constraint at the PU receiver. This letter studies the ergodic capacity of spectrum-sharing systems in fading channels. The ergodic capacity expression along with the optimal power allocation scheme is derived considering both the average transmit and received power constraints. The capacity function in terms of the two power constraints is found to be divided into transmit power limited region, received power limited region and dual limited region. Numerical results in Rayleigh fading channels are presented to verify our analysis.
