Spectrum sensing is critically important for cognitive radio, an emerging solution to the
spectrum congestion and low usage of licensed spectrum. Energy detection is a promising …

A comprehensive performance analysis of the energy detector over fading channels with
single antenna reception or with antenna diversity reception is developed. For the no …

Energy detection (ED) is a simple and popular method of spectrum sensing in cognitive
radio systems. It is also widely known that the performance of sensing techniques is largely …

Cooperative spectrum sensing has proven its efficiency to detect spectrum holes in cognitive
radio network (CRN) by combining sensing information of multiple cognitive radio users. In …

Spectrum sensing for cognitive radio allows a secondary user to detect spectrum 'holes' and
to opportunistically exploit this space for unlicensed communication. Blind spectrum sensing …

Reliable spectrum sensing is the very task upon which the entire operation of cognitive radio
rests. Blind sensing of spectral-holes using a radiometer (energy detectors) is one of the …

As a key technology of network inference, topology sensing plays an important role in
understanding, explaining and predicting network behavior. Majority of existing studies …

Increasing number of antennas are closely packed in emerging multiantenna systems and
correlation among them can no longer be ignored. In this paper, such a multiantenna …

In cognitive radio network (CRN), secondary users (SUs) try to sense and utilize the vacant
spectrum of the legitimate primary user (PU) in an efficient manner. The process of …

In cognitive radio communication, spectrum sensing plays a vital role in sensing the
existence of the primary user (PU). The sensing performance is badly affected by fading and …
