Remote Geophysical Observatory in Antarctica with HF data transmission: a Review
(, , 2014-07)
The geophysical observatory in the Antarctic Spanish Station Juan Carlos I (ASJI) in Livingston Island has been monitoring the magnetic field in the Antarctic region for more than fifteen years. In 2004, ...
An FPGA Scalable Software Defined Radio Platform Design for Educational and Research Purposes
(, , 2016-06)
In a digital modem design, the integration of the Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) with the core processor is usually a major issue for the designer. In this ...
Review of Wireless Acoustic Sensor Networks for Environmental Noise Monitoring in Smart Cities
(, , 2019-05)
Nowadays, more than half of the world’s population lives in urban areas. Since this proportion is expected to keep rising, the sustainable development of cities is of paramount importance to guarantee ...
Polarization diversity in a long-haul transequatorial HF link from Antarctica to Spain
(, , 2017-01)
This paper describes a set of experiments which examine the feasibility of applying polarization diversity to a 12,760 km ionospheric link from Livingston Island (62.6°S, 60.4°W), South Shetlands, to ...
Digital Transmission Techniques for a Long Haul HF Link: DS-SS vs. OFDM
(, , 2014-06)
This paper presents two digital transmission techniques for long haul ionospheric links. Since2003 we have studied the HF link between the Antarctic Spanish Base, Juan Carlos I, and Spain; and wehave ...
An FPGA-Based WASN for Remote Real-Time Monitoring of Endangered Species: A Case Study on the Birdsong Recognition of Botaurus stellaris
(, , 2017-06)
Fast environmental variations due to climate change can cause mass decline or even extinctions of species, having a dramatic impact on the future of biodiversity. During the last decade, different ...
Survey of Environmental Noise in the Port of Barcelona
(, , 2018-05-24)
Ports and harbours are logistic nodes characterized by noisy operations. Noise pollution analysis iscomplicated, because several types of noise usually can occur in the same area: ferries, cruises, ...
Preliminary Results of DYNAMAP Noise Mapping Operations
(, , 2018-08-26)
DYNAMAP, a European Life project, aims at developing a dynamical acoustic map of large urban areassuch as the city of Milan based on a limited number of noise monitoring stations. Generally, traffic ...
A WASN-Based Suburban Dataset for Anomalous Noise Event Detection on Dynamic Road-Traffic Noise Mapping
(, , 2019-05)
Traffic noise is presently considered one of the main pollutants in urban and suburban areas. Several recent technological advances have allowed a step forward in the dynamic computation of road-traffic ...
