Dynamic Spectrum Leasing (DSL) in Dynamic Channels
2010 Edition, May 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Dynamic Spectrum Leasing (DSL) was recently proposed in [1]-[4] as a new way to achieve dynamic spectrum sharing (DSS). Unlike previously considered dynamic spectrum access (DSA) proposals, DSL allows for the spectrum...

A dynamic spectrum leasing (DSL) framework for spectrum sharing in cognitive radio networks
2009 Edition, November 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose dynamic spectrum leasing (DSL) as a new paradigm for dynamic spectrum sharing (DSS) in (cognitive) radio networks to improve spectrum utilization. In contrast to exiting hierarchical dynamic spectrum access...

Distributed Dynamic Spectrum Leasing (D-DSL) for Spectrum Sharing over Multiple Primary Channels
2011 Edition, Volume 10, January 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose a new architecture for dynamic spectrum sharing called the distributed dynamic spectrum leasing (D-DSL) and a game-theoretic framework for its implementation on a cognitive radio network. In D-DSL, each available frequency...

Efficient Dynamic Spectrum Sharing in Cognitive Radio Networks: Centralized Dynamic Spectrum Leasing (C-DSL)
2010 Edition, Volume 9, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose the concept of centralized dynamic spectrum leasing (C-DSL), in which multiple primary users belonging to the same primary system participate in the spectrum leasing process with secondary users (potential...

Efficient spectrum sharing with autonomous primary users: Distributed dynamic spectrum leasing (D-DSL)
2010 Edition, December 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper we introduce a new architecture for dynamic spectrum sharing called the distributed dynamic spectrum leasing (D-DSL) and a game theoretic framework for its implementation on a cognitive radio network. In D-DSL, it is...

Performance evaluation of three dynamic channel access strategies for spectrum leasing in CRNs
2015 Edition, June 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Spectrum leasing in cognitive radio networks (CRNs) allows the primary network (PN) to lease a certain fraction of its licensed bandwidth to the secondary network (SN). The motivation for such a concept is to enhance the performance of SNs while improving channel...

Dynamic Channel Allocation in Small Cells
2018 Edition, August 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The inter-cell interference coordination techniques which include frequency reuse and Dynamic Channel Allocation (DCA) play a vital role in improving the spectrum efficiency. The techniques of frequency reuse are very sophisticated. Depending on the traffic demand,...

Dynamic Channel Modeling for Mode-Division Multiplexing
2017 Edition, Volume 35, June 15, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Environmental perturbations, such as wind, mechanical stress, temperature, and lightning, impose microsecond-time-scale changes to the transfer matrix of a multimode fiber (MMF), necessitating adaptive multiple-input multiple-output (MIMO) equalization to track the time-varying channel. It...

Dynamic channel modeling for mode-division multiplexing
2016 Edition, July 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose a dynamic channel model to describe time-varying polarization- and spatial-mode coupling in few-mode fibers caused by fast environmental perturbations. We employ the model to study the tracking performance of adaptive multi-input multi-output equalization algorithms.
