Adaptive Double Threshold based Spectrum Sensing for Cognitive Radio Networks
Rapid growth of wireless communication and limited spectrum availability to support the applications and services, has led to the development of cognitive radio as promising solution to address the problem of spectrum scarcity. Spectrum sensing is one of the fundamental functions towards the implementation of the cognitive radio concept in wireless communication. In this paper, we present an ad...
متن کاملTwo-stage detectors based on multiple Antennas with Adaptive Double-Threshold in Cognitive Radio Networks
In this paper, we propose a two-stage spectrum sensing (SS) scheme in cognitive radio networks (CRN). First stage consists of multiple antennas (M) based energy detector (ED) with fixed single threshold (MA_ED_FT) and if required, second stage comprised of ED with adaptive double threshold (ADT) is invoked. Numerical results show that proposed scheme optimizes detection performance and outperfo...
متن کاملAdaptive Double-Threshold Based Energy and Matched Filter Detector in Cognitive Radio Networks
In this paper we propose a new cooperative spectrum sensing method using adaptive double threshold energy and matched filter detector in cognitive radio networks. The energy detector (ED) performance is highly degraded under noise uncertainty condition. Also, ED cannot well differentiate between the signal and noise, if the detected observational value of the primary user (PU) lies in the confu...
متن کاملCooperative Adaptive Threshold Based Energy and Matched Filter Detector in Cognitive Radio Networks
CR (cognitive radio) is the key technology for unlicensed SUs (secondary users) to exploit the unused spectrum of PUs (primary users) via opportunistic spectrum access. In this paper, we propose a new spectrum sensing method using cooperative adaptive threshold based on energy and matched filter detector in cognitive radio networks. The ED (energy detector) is highly susceptible to noise uncert...
متن کاملAdaptive Double Threshold with Multiple Energy Detection Technique in Cognitive Radio
The Cognitive Radio (CR) network is a system which lends help at the time of scarcity in spectrum. One of the process by which CR senses the spectrum is energy detection method with a fixed single threshold. When energy levels fall below the threshold, secondary user is permitted to use the spectrum of the primary user. It is shown by simulation results that having two levels of threshold i.e.,...
