This paper<sup>1</sup> 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(More)
Listeners suffering from presbycusis (age-related hearing loss) often report difficulties when attempting to understand vocal announcements in public spaces. Current solutions that improve speech intelligibility for hearing-impaired subjects mainly consist of customized solutions, such as hearing aids. This study proposes a more generic strategy, which(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&apos;s) to estimate the existence of(More)
