Dynamic Spectrum Management With Spherical Coordinates
IEEE Transactions on Signal Processing, 2014Multiuser interference, i.e., crosstalk, is the main bottleneck for digital subscriber lines (DSL) technology. Dynamic spectrum management (DSM) mitigates crosstalk by focusing on the multiuser power/frequency resource allocation problem, and it can provide formidable gains in performance.

Dynamic Spectrum Management: Complexity and Duality
IEEE Journal of Selected Topics in Signal Processing, 2008Consider a communication system whereby multiple users share a common frequency band and must choose their transmit power spectral densities dynamically in response to physical channel conditions. Due to co-channel interference, the achievable data rate of each user depends on not only the power spectral density of its own, but also those of others in ...

2015 13th International Conference on Telecommunications (ConTEL), 2015
Recently, Dynamic Spectrum Access (DSA) and Cognitive Radio (CR) have received increasing interest from the research community, raising high expectations related to spectrum sharing between mobile operators or exploiting white spaces (e.g. fixed wireless access in rural areas through the usage of locally unused TV spectrum).

Dynamic spectrum management in DSL with asynchronous crosstalk
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011Dynamic spectrum management (DSM) aims to optimally allocate per-user transmit spectra so that the effect of multiuser interference (crosstalk) is minimized and the capabilities of the network are maximized. Work on DSM has progressed considerably over the past decade.

Option-based Dynamic Management of Wireless Spectrum
2009 Next Generation Internet Networks, 2009Dynamic spectrum management makes it possible for the owner of usage rights on some frequency blocks to sublet each of them in real time and for a limited period of time. As a softer implementation with respect to the spot market a two stage assignment is here proposed through the use of options, which give buyers the right to purchase the usage right ...

A spectrum-overlapped resource management in dynamic spectrum control technique
2008 IEEE 19th International Symposium on Personal, Indoor and Mobile Radio Communications, 2008This paper proposes a spectrum-overlapped resource management (SORM) technique using a dynamic spectrum control (DSC) and turbo equalizer for flexible frequency domain resource management under multiuser conditions. In the proposed technique, discrete spectrum of the transmitted signal is mapped onto spectrum components having the highest channel gain ...

Spectrum Management over Dynamic Spectrum Access based HetNets
2019 IEEE International Symposium on Dynamic Spectrum Access Networks (DySPAN), 2019This paper presents spectrum management in dynamic spectrum access (DSA) based 5G heterogeneous wireless networks (HetNets). Current literature studies architectures and signaling mechanisms for network selection, but rarely discuss proper bandwidth management for users over multiple HetNets.

Greener Copper with Dynamic Spectrum Management
2009Power-saving benefits of Dynamic Spectrum Management (DSM) result from its increased robustness to channel and noise changes, as in this paper. A proposed intermittent noise model enables evaluation of the performance of DSM algorithms. Polite Level-1 DSM algorithm consumes much less power than non-polite DSL management algorithms in the presence of ...

Dynamic spectrum reallocation via autonomic management
2009 IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks & Workshops, 2009We discuss a “self-management” concept, suitable for the description of autonomic spectrum reallocation operations through dynamic resource allocation and control processes, for an effective realization of the Future Internet (FI) vision. We introduce a specific targeted methodology, in the form of the Generic Cognitive Cycle Model, including three ...

Distributed and dynamic spectrum management in airborne networks
MILCOM 2015 - 2015 IEEE Military Communications Conference, 2015Airborne network plays an important role in operations of Air Force. Due to the rapidly-changing topologies, limited wireless communication spectrum, latency, and priorities of tasks, it is vitally important to have dynamic spectrum management between aircrafts and base station in airborne networks.
