Cooperative wideband spectrum sensing over Rician and Nakagami fading channels
2015 Edition, December 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Spectrum sensing technique is the most crucial factor that determines the performance of Cognitive Radio (CR) systems. Wideband spectrum sensing using Nyquist and sub Nyquist sampling rates proved to have better performance than other types of...

Cooperative sequential compressed spectrum sensing over wide spectrum band
2015 Edition, June 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Cognitive radio (CR) techniques promise to significantly increase the available spectrum thus wireless bandwidth. With the increase of spectrum allowed for CR, it is critical and challenging to perform efficient wideband sensing. We propose an integrated...

Double-threshold based cooperative spectrum sensing over imperfect channels
2015 Edition, March 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper proposes a hybrid double-threshold based energy detector (HDTED) for cooperative spectrum sensing over imperfect channels in cognitive wireless radio networks (CWRNs). The proposed HDTED improves the sensing reliability in...

Energy-based Bayesian spectrum sensing over ++--¦ fading channels
2015 Edition, July 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we study the performance of energy detection for spectrum sensing over the η-μ fading channel, following a Bayesian approach. We derive an infinite series expression for the probability of error, which is a convex...

Diversity of spectrum sensing over frequency selective Rayleigh fading channels
2016 Edition, May 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In cognitive radio systems, diversity of missed detection probability reflects the reliability of spectrum sensing. In this paper, we quantify the diversity order of missed detection probability over a Rayleigh frequency-selective channel with...

Cooperative Spectrum Sensing over Imperfect Channels
2008 Edition, November 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Cognitive radio has emerged as an innovative approach able to cope with the spectral limitations. Cognitive radio networks rely on detecting whether a particular segment of the radio spectrum is currently in use and to exploit the temporarily unused...

Cooperative Spectrum Sensing over ?-μ Fading Channel
2012 Edition, November 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, detection performance of an energy detector is exploited under the ?-μ fading channel model.The ?-μ is a general fading channel model that includes the Rice and the Nakagami-m models as special cases. The receiver operating characteristics (ROC)...

Performance of Cooperative Spectrum Sensing over Non-Identical Fading Environments
2011 Edition, Volume 59, December 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Different from previous works in cooperative spectrum sensing that assumed the sensing channels independent identically distributed (i.i.d.), we investigate in this paper the independent but not identically distributed (i.n.i.d.) situations. In particular, we derive the...
