Abstract:
This paper proposes a novel spectrum sensing scheme for dynamic traffic circumstances, where a Primary User (PU) signal may randomly depart or arrive during the sensing period, and thus, the conventional schemes developed under the assumption of the static traffic circumstances perform poorly. In the proposed scheme, a sensing period is partitioned into several sub-periods and the final decision on the existence of the PU signal is made by combining sensing decisions during each subperiod. From numerical results, it is confirmed that the proposed scheme has an improved detection performance compared with those of the conventional schemes.
