Efficient Spectrum Management among Spectrum Sharing UMTS Operators
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011Dynamic spectrum management is a promising solution for network operators to efficiently utilise the limited radio spectrum and guarantee operator's profit by increasing capacity as well as generating more spectrum opportunities for opportunistic use.

Energy-efficient spectrum access in Cognitive Radio
2013 IEEE 24th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2013Cognitive radio (CR) and energy-efficient design have emerged as two promising techniques to achieve high spectrum efficiency (SE) and energy efficiency (EE), respectively. In this paper, we study energy-efficient opportunistic spectrum access strategies for an orthogonal frequency division multiplexing (OFDM)-based CR network with multiple secondary ...

Energy Efficiency of Spectrum-Sharing Communication Systems
2015 IEEE Global Communications Conference (GLOBECOM), 2014Energy efficiency is of paramount importance for studying spectrum-sharing green communications. We provide some understanding on the energy efficiency of spectrum-sharing systems which are subject to an average interference power constraint. The results present some interesting insight for designing spectrum-sharing systems.

Spectrum Efficiency in Distributed Antenna Systems
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011The distributed antenna system (DAS) is a promising system to provide high data rate for future wireless communications, since it can reduce the radio transmission distance. This paper aims to investigate the average spectrum efficiency and the cell edge spectrum efficiency in the downlink transmission of the DAS.

Spectrum Efficiency at the Extensive and Intensive Edges
Wireless Personal Communications, 2017Future 5G architectures will need access to additional spectrum either at the extensive edge (accessing hitherto unused spectrum or refarming assigned spectrum) or at the intensive edge (making more productive use of used spectrum). A full understanding and pursuit of spectrum efficiency dividends will be a deciding factor in the successful deployment ...

Spectrum alignment: efficient resequencing by hybridization.
Proceedings. International Conference on Intelligent Systems for Molecular Biology, 2001Recent high-density microarray technologies allow, in principle, the determination of all k-mers that appear along a DNA sequence, for k = 8 - 10 in a single experiment on a standard chip. The k-mer contents, also called the spectrum of the sequence, is not sufficient to uniquely reconstruct a sequence longer than a few hundred bases. We have devised a
