Cross-Layer Design in Dynamic Spectrum Sharing Systems
We consider a dynamic spectrum sharing system consisting of a primary user, whose licensed spectrum is allowed to be accessed by a secondary user as long as it does not violate the prescribed interference limit inflicted on the primary user. Assuming the Nakagami-m block-fading environment, we aim at maximizing the performance of secondary user’s link in terms of average spectral efficiency (AS...
متن کاملCognitive Radio and Dynamic Spectrum Sharing Systems
The vision behind software radio (SR) is to realize the communication specific signal processing of a radio as far as possible on programmable hardware. An ideal SR samples the received signal directly at the antenna, and its hardware consists of a general purpose processor that is connected with analog-to-digital and with digital-to-analog converters. A radio that uses an analog radio frontend...
متن کاملA Review of Cross-layer Design in Dynamic Spectrum Access for Cognitive Radio Networks
Cognitive Radio (CR) is an intelligent radio that can dynamically access the radio spectrum. Secondary users in Cognitive Radio Network (CRN) can access the licensed spectrum without causing harmful interference to primary users. The performance of cognitive radio networking functionalities depends on the properties of the spectrum band in use. This necessitates a crosslayer design in the entir...
متن کاملSpectrum Sharing In Dynamic Spectrum Access Networks
A study by Federal Communication Commission shows that most of the spectrum in current wireless networks is unused most of the time, while some spectrum is heavily used. Recently dynamic spectrum access (DSA) has been proposed to solve this spectrum inefficiency problem, by allowing users to opportunistically access to unused spectrum. One important question in DSA is how to efficiently share s...
متن کاملDynamic Cross-Layer Spectrum Allocation for Multi-Band High-Rate UWB Systems
In this paper, we investigate a new approach for the spectrum allocation in UWB systems. This approach consists in a cross-layer scheme that takes into consideration the different users channel quality and quality of service (QoS) requirements. The new scheme is based on the WiMedia solution proposed for multiband OFDM UWB systems. The main objective is to propose a lowcomplexity solution for t...
