In this survey paper, we characterize the learning problem in cognitive radios (CRs) and
state the importance of artificial intelligence in achieving real cognitive communications …

Over the past decade or so, the wireless industry has undergone many significant changes.
Radio systems have moved toward forming heterogeneous wireless networks …

Distributing Radio Resource Management (RRM) in heterogeneous wireless networks is an
important research and development axis that aims at reducing network complexity. In this …

The cognitive radio network (CRN), as a promising technique in future wireless
communication networks, shall execute some critical functionalities to enhance existing …

In this paper, we propose an adaptive-power-control scheme for a cognitive radio system
(CRS) in a Rayleigh fading channel. By allowing transmit power adaptation at the secondary …

We report on our recent progress in the manipulation and cooling of a magnetically guided,
high-flux beam of Rb 87 atoms. Typically, 7× 10 9 atoms per second propagate in a …

It is expected that a number of heterogeneous radio access technologies will be available
simultaneously at a single wireless terminal in next generation wireless networks. This …

This paper examines the international, inter-organizational collaboration processes for the
development of cognitive radio, which will be at the basis of potentially profound changes in …

IEEE P1900. 4 is an emerging standard for optimized radio resource utilization where
cognitive radio technologies are used for efficient spectrum utilization. In this paper, we …
