Throughput analysis for cognitive radio networks with multiple primary users and imperfect spectrum sensing
In cognitive radio networks, the licensed frequency bands of the primary users (PUs) are available to the secondary user (SU) provided that they do not cause significant interference to the PUs. In this paper, we analyzed the normalized throughput of the SU with multiple PUs coexisting under any Frequency Division Multiple Access (FDMA) communication protocol. We consider a cognitive radio tran...
متن کاملCognitive Spectrum Sensing with Multiple Primary Users in Rayleigh Fading Channels
Accurate detection of white spaces is crucial in cognitive radio networks. Initial investigations show that the accurate detection in a multiple primary users environment is challenging, especially under severe multipath conditions. Among many techniques, recently proposed eigenvalue-based detectors that use random matrix theories to eliminate the need of prior knowledge of the signals proved t...
متن کاملPerformance Analysis of Correlated Multiple Antenna Spectrum Sensing Cognitive Radio
We derive probability of detection Pd and false alarm Pf for spectrum sensing cognitive devices, employing correlated multiple antenna elements using linear test statistic. Detection performance of such sensors is severely degraded due to the correlation among antennas, in addition to that fading channel conditions may further deteriorate the performance. We propose a simple hard decision fusio...
متن کاملQuickest Spectrum Sensing with Multiple Antennas: Performance Analysis in Various Fading Channels
Traditional wireless networks are regulated by a fixed spectrum assignment policy. This results in situations where most of the allocated radio spectrum is not utilized. In order to address this spectrum underutilization, cognitive radio (CR) has emerged as a promising solution. Spectrum sensing is an essential component in CR networks to discover spectrum opportunities. The most common spectru...
متن کاملMultiple Detectors Based Analytical Performance of Spectrum Sensing
A key challenge in operating cognitive radios (CRs) in a self-organizing (ad hoc) network is how to adaptively and efficiently utilize spectrum resources keeping in mind that no interference is caused to primary users and also that no spectrum is rendered unused when a secondary user is waiting for access. Detecting the spectrum holes using one detector can be insufficient for increasing second...
