Currently, the IEEE Standards Association is very active in the framework of cognitive radio with an aim to provide a bridge between research results, implementation, and widespread deployment of this new communication paradigm. This article reports recent developments within the IEEE Dynamic Spectrum Access Network Standards Committee1 on dynamic spectrum access networks with particular consideration...
This paper presents the types and classes of sensing related information to be exchanged among the entities in cognitive radio systems. The information was extracted by analyzing distributed spectrum sensing use cases and has been checked for the consistence with available sensing techniques and sensors' capability. This paper also introduces IEEE P1900.6 WG recent activities on standardizing the...
Spectrum sensing is a key component of cognitive radio (CR) system to understand its radio frequency (RF) environment. One critical challenge in spectrum sensing is detection of weak signals in particular in an indoor environment. Distributed spectrum sensing can address this shortcoming by providing a combined data from spatially distributed sensors. This approach often achieves higher sensitivity...
This paper introduces NICT's two current on-going projects regarding heterogeneous type and spectrum sharing type cognitive wireless network: Project CWC (Cognitive Wireless Cloud) and Project ASTRA (Advanced Spectrum-Management Technology for Radio Access innovation). For both projects, this paper summarizes the scope, usage model, system requirement, system architecture, prototyping, and standard...
This paper introduces two cognitive radio (CR) systems: (a) heterogeneous type CR and (b) spectrum sharing type CR regarding its definition, usage model, fundamental system architecture, and developed prototype.
