Abstract
In this paper, we propose and simulate a collaborative cyclostationary spectrum sensing for the advanced television systems committee digital television (ATSC DTV) signals. In order to enhance the spectrum sensing performance, we employ collaborative sensing system. And an equal gain combining (EGC) scheme is adopted for combining local decision results. A wireless communication channel considered in this paper is a Gaussian channel. For evaluating the spectrum sensing performance, a detection probability is derived. We consider two kinds of decision rules which are AND and OR decision rule. From simulation results, it is confirmed that in case of OR decision rule, the spectrum sensing performance is improved as the number of collaborative sensing point increases, while AND decision rule is decreased. The results of this paper can be applied to implement cognitive radio (CR) systems.
