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 ...
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 ...
Narrowband and Wideband Channel Sounding of an Antarctica to Spain Ionospheric Radio Link
(, , 2015-09)
La Salle and Ebro Observatory have been involved in remote sensing projects in Antarctica for the last 11 years (approximately one solar cycle). The Ebro Observatory has been monitoring and analyzing ...
Detection of Anomalous Noise Events on Low-Capacity Acoustic Nodes for Dynamic Road Traffic Noise Mapping within an Hybrid WASN
(, , 2018-04)
One of the main aspects affecting the quality of life of people living in urban and suburban areas is the continuous exposure to high road traffic noise (RTN) levels. Nowadays, thanks to Wireless Acoustic ...
Real-Time Distributed Architecture for Remote Acoustic Elderly Monitoring in Residential-Scale Ambient Assisted Living Scenarios
(, , 2018-08)
Ambient Assisted Living (AAL) has become a powerful alternative to improving the life quality of elderly and partially dependent people in their own living environments. In this regard, tele-care and ...
