—This paper 1 deals with spectrum sensing techniques used to efficient utilization of limited spectrum resource. The most used technique is the energy detector as it is the simplest one for real time implementation and performs well for high SNR. This paper is concerned with this well known method and introduces an enhanced energy detector, in order to(More)
In this paper a cooperative spectrum sensing system based on IEEE 802. 22 standard is proposed and modeled as cooperative game theory scheme. The proposed method considers each secondary user as a single sensing terminal that implies energy detection as spectrum sensing method with different signal to noise ratios (SNR's) to estimate the existence of(More)
