Cooperative Spectrum Sensing over Non-Identical Nakagami Fading Channels
2011 Edition, May 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Previous works in cooperative spectrum sensing assumed that the channels for sensing and reporting are independent identically distributed (i.i.d). A more practical and appropriate assumption, however, should be that the sensing channels and...

Entropy and Energy Detection-based Spectrum Sensing over F Composite Fading Channels
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we investigate the performance of energy detection-based spectrum sensing over F composite fading channels. To this end, an analytical expression for the average detection probability is firstly derived. This expression is then...

Multi-peaks accumulation based spectrum sensing over multipath channel
2014 Edition, October 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Spectrum sensing is one of key technologies in cognitive radio to obtain radio environment knowledge. However, the regular correlator detector suffers from the inference of multipath fading channel on the primary signal. In this paper we propose a...

Soft Combining for Cooperative Spectrum Sensing over Fast-Fading Channels
2014 Edition, Volume 18, February 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose soft combining methods for cooperative spectrum sensing in cognitive radio networks over fast-fading channels. In fast-fading environment, it is difficult to obtain the exact probability distribution of the total...

Performance analysis for spectrum sensing over fading reporting channels
2012 Edition, April 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Cognitive radio (CR) technology is an emerging technology to improve the utilization of radio spectrum. Cooperative sensing is used to enhance the efficiency of the cognitive radio network (CRN). In this paper, we consider the probability of...

Entropy Based Weighted Decision Combining for Collaborative Spectrum Sensing over Byzantine Attack
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Collaborative spectrum sensing (CSS) as a promising solution is widely adopted for identifying available spectrum. However, such cooperation is vulnerable to be threatened by Byzantine attack. To defend against such attack, a low-complexity entropy-based...

Robust Collaborative Spectrum Sensing over non-ideal reporting channels
2013 Edition, November 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Collaborative Spectrum Sensing (CSS) is well known for its applicability to combat fading and shadowing effects in Cognitive Radio (CR) networks. In this paper, we show the ineffectiveness of conventional CSS techniques over non-ideal...

Performance analysis of multi-antenna-based spectrum sensing over fading channel
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The performance of multi-antenna spectrum sensing over Nakagami fading channel is analyzed when the received signals from multiple antennas are uncorrelated. Firstly, maximal ratio combining, equal-gain combining and selection combining are employed to...

Cooperative spectrum sensing over generalized fading channels based on energy detection
2018 Edition, Volume 15, May 1, 2018 - China Communications Magazine Co. Ltd.

This paper analyzes the unified performance of energy detection (ED) of spectrum sensing (SS) over generalized fading channels in cognitive radios (CRs). The detective performance of SS will be obviously affected by fading...
