Empirical modelling of spectrum use and evaluation of adaptive spectrum sensing in dynamic spectrum access networks
… applications yields a growing demand for radio spectrum. However, most of the commercially interesting spectrum has been assigned to various services and allocating further spectrum is a cumbersome process. Some authors claim that current policies are inefficient and cause an artificial spectrum …

A learning-based scheme to optimise a cognitive handoff
… standards promotes the development and use of several spectrum-sharing strategies. From the noted results, machine-learning techniques have paved a direction for radio protocols to achieve better levels of performance. With their definition, efficient learning practices and the use of …

Misuse Detection in Dynamic Spectrum Access Networks
With dynamic spectrum access emerging as an important paradigm for efficient spectrum use, mechanisms are required to ensure disciplined spectrum access by secondary users. This must be done without requiring secondary users to disclose private data, such as their exact usage pattern or identities …

Assignment of exclusive spectrum licenses in Japan : use of an auction for the licensee selection process
The demand for spectrum resources has increased in the past decade due to the flourishing wireless industry worldwide. This change requires Japan's Ministry of Internal Affairs and Communications (MIC) to establish a transparent, fair and efficient spectrum allocation process that will enable it to …

Experimental investigation and analyses of continuous type hybrid photoelectrochemical hydrogen production systems
… the future CO2-free energy infrastructure. When used in fuel cells, H2 is converted to water and it gives little or zero exhaust of greenhouse gases. For H2 economy to succeed, it needs to be produced in a clean, sustainable, reliable, and feasible way. The main objective of this study is to …

Securing Cognitive Radios with a Policy Enforcer and Secure Inter-component Transport Mechanisms
… with two significant problems with regard to spectrum use --- spectrum scarcity and deployment difficulties. It is widely believed that Software Defined Radios (SDRs) and Cognitive Radios (CRs) are the key enabling technologies to address these problems. The reconfigurability of SDRs combined …

xG-SS: Towards a Hardware and Simulation Experimentation Platform for Spectrum Sharing with 5G NR-U
… wireless systems and the increasing demand for spectrum to accommodate a growing number of users and diverse services have necessitated novel ap- proaches to spectrum sharing. Among these approaches, distributed spectrum sharing offers the most flexibility by allowing real-time spectrum use …

Aplicación del análisis tecno-económico a la gestión del espectro radioeléctrico. El caso de la reutilización de las bandas GSM en Europa
… of the traditional “command-and-control” radio spectrum management policy towards a more flexible, market-based one has been undoubtedly one of the most important challenges of the European public policy on the telecoms sector. The main aims behind this reform are to improve the efficiency in …
