N2 - Cognitive radio, which is expected to yield high frequency utilization, requires a highly reliable sensing technique. Cooperative sensing techniques have been studied to meet this demand. However, conventional techniques have high false alarm rates. To solve this problem, we propose a new cooperative sensing technique in which the received power levels at several radio stations are multiplied by different weights and added. Whether or not radio waves are present is determined from this total power level. A computer simulation demonstrates that the proposed technique offers a lower false alarm rate than conventional techniques while satisfying the misdetection rate. copyright
