Cogitive radio networks (CRNs) require high capacity and accuracy to detect the presence of licensed or primary users (PUs) in the sensed spectrum. In addition, they must correctly locate the spectral opportunities (holes) in order to be available to

Cognitive radios represent a real alternative to the scarcity of the radio spectrum. One of the primary tasks of these radios is the detection of possible gaps in a given bandwidth used by licensed users (called also primary users). This task, called

In this work, a novel multiband spectrum sensing technique is implemented in the context of cognitive radios. This technique is based on multiresolution analysis (wavelets), machine learning, and the Higuchi fractal dimension. The theoretical contrib

In this work, three specific machine learning techniques (neural networks, expectation maximization and k-means) are applied to a multiband spectrum sensing technique for cognitive radios. All of them have been used as a classifier using the approxim

In this work, two novel methodologies for the multiband spectrum sensing in cognitive radios are implemented. Methods are based on the continuous wavelet transform (CWT) and the multiresolution analysis (MRA) to detect the edges of available holes in

Electronic low-cost devices are an important part of the market nowadays. This trend has reached several products, that in the past just were available for academic institutions or the industry. In this regard, software-defined radio (SDR) is an impo

Clock synchronization in underwater wireless sensor networks (UWSN) is a key procedure for the operation of this type of networks. Besides, due to the characteristics of the underwater channel, UWSNs face challenging constraints that make them differ

After moving to a new city, an electronics professor had problems finding a place to live, so he chose the option of sharing a house. The place had a good environment-until some flatmates obtained new jobs. After that, more people were arriving at th

This paper focuses on the design of methods which enable unlicensed devices to use the frequency spectrum already allocated to rotating radar systems without causing interference to those radars. We first present a database-assisted spectrum sharing/
