In the context of this PhD thesis defense, Luis Blanco presents his work realized at CTTC. This dissertation deals with different subset selection problems in wireless communications systems. These type of problems have a combinatorial nature, which makes them computationally intractable for medium and large-scale sizes. In particular, two different types of problems are addressed [...]

The  Communication Systems Division, Communication Networks Division and Communication Technologies Division of the CTTC are searching for research candidates. Go to careers to apply now.

Vladimir Trukhaev, a high-school student from the St. Paul’s School (Barcelona), visited CTTC after being awarded a Richi Talent Scholarship. During his one-week stay at CTTC, Vladimir was introduced to the field of machine learning by Javier Matamoros and David Gregoratti, two of our researchers in the Communications Systems Division. The term machine learning comprises [...]

In the context of this PhD thesis defense, Miguel Calvo-Fullana presents his work realized at CTTC. Long thought to be an unattainable ambition, self-sustainable and green-powered wireless networks are rapidly becoming a reality. This is driven by recent hardware improvements in what is known as Energy Harvesting (EH). This technology makes it possible for devices [...]

ABSTRACT: The potential of Free/Libre Open Source Software (FLOSS) as a way to increase competitiviness has been emphasized by many studies as well as public policies and funding programs. While many research and innovation projects and organizations adopt FLOSS in order to foster the dissemination of their results, the translation to marketable products and services remains [...]

In the context of this PhD thesis defense, Pol Henarejos presents his work realized at CTTC. Radiocommunication systems have evolved significantly in recent years in order to meet present and future demands. Historically, time, frequency and more recently, spatial dimensions have been used to improve capacity and robustness. Paradoxically, radiocommunications that leverage the polarization dimension [...]

ABSTRACT: A new two-dimensional modulation technique called Orthogonal Time Frequency Space (OTFS) modulation designed in the delay-Doppler domain is introduced as a waveform ideally suited to new 5G use cases. Through this design, which exploits full diversity over time and frequency, OTFS coupled with equalization converts the fading, time-varying wireless channel experienced by modulated signals [...]

The high school students Carles Bosch and Ariel Piqué were awarded a Richi Talent Scholarship to visit the CTTC during summer During this short-term visit, the students received guidance to work on their own research projects in the area Visible Light Communications (VLC). The instruction was provided by Alexis Dowhuszko and Pol Henarejos, two resarchers of the [...]

Open source NS-3 Network Simulator now has LTE-U capability that supports leading edge features from SpiderCloud’s Enterprise RAN. SpiderCloud Wireless, Inc., the leading provider of scalable small cell systems, and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), the leading resource organization in communication technologies, today announced a successful collaboration that simulates SpiderCloud’s LTE-U performance and [...]

CTTC is pleased to announce the 3-day course Ground-Based SAR deformation monitoring: data analysis organized by the Geomatics Division of the CTTC and sponsored by IDS (www.idscorporation.com). The course will cover the relevant aspects of GBSAR data analysis to understand advantages and limitations of this new technique and to correctly exploit and interpret its data. [...]

During the month of July, CTTC will host in different weeks, 4 high school students in the context of the Richi Talent program and selected by the Richi Foundation in order to work towards different Science and Technology challenges proposed by different researchers at CTTC. The supervisors of these activities are: Pol Henarejos, Alexis Dowhuszko, [...]

The HEIMDALL (MULTI-HAZARD COOPERATIVE MANAGEMENT TOOL FOR DATA EXCHANGE, RESPONSE PLANNING AND SCENARIO BUILDING) project aims at improving preparedness of societies to cope with complex crisis situations by means of providing integrated tools to support efficient response planning and the building of realistic multidisciplinary scenarios. Remote Sensing Department of the CTTC, as one of the [...]

The CTTC organizes the IEEE Wireless Communications and Networking Conference, on April 15th-18th, 2018. This edition will take place in Barcelona. IEEE WCNC is the only IEEE conference focused exclusively on wireless research, technology, and applications. It brings together thought leaders from industry, academia, government agencies and other institutions to exchange information and ideas on [...]

The CTTC recently signed an agreement with InterDigital to collaborate on the development of New Radio (NR) concepts targeted for 5G Phase 2. NR, the global standard being driven by 3GPP for a new 5G air interface, is a continuing part of the mobile broadband evolution to deliver on the requirements of 5G. According to [...]
