Spectrum sensing is a key technology in cognitive radio (CR). It provides the CR system with available vacant channels list by sensing the spectrum environment over a wide frequency band. However, local sensing by single node will be compromised if the sensing node experiences shadowing or fading effect. Cooperative spectrum sensing is derived to solve this problem. In this paper, we propose an adaptive cooperative spectrum sensing scheme by using the optimal data fusion rule. To implement such… CONTINUE READING
