ABSTRACT: High data-rate communication systems require the transmission of radio frequency (RF) signals which are modulated in both amplitude and phase, presenting peak power envelope swings exceeding ten times their average power levels. In wireless communication systems, it is a significant challenge to transmit high peak-to-average-power-ratio signals whilst maintaining a high degree of energy efficiency. However, [...]

The SCAVENGE project celebrates its 5th Progress Meeting. This time, the meeting will be held at CTTC premises, in Castelldefels, in September 27th and 28th. The meeting is open, so you all are welcome to attend. Please send us an e-mail to pm@cttc.cat if you are interested in taking part of the meeting.

On the 21st September 2018, the 1st CTTC Workshop will be held at the Melià Hotel, in Sitges. The aim of the session is to get together all the researchers at CTTC so that they can share and put in common their personal works in poster sessions. Apart from this, the workshop counts with several [...]

ABSTRACT: Communication at mmWave frequencies will play a key role in next generation 5G cellular networks. However, mobile scenarios are the most challenging for mmWave cellular systems, due to the high propagation loss, the relatively small coverage area of individual cells, and rapid channel dynamics caused by blockage events. In this talk, Michele Polese will [...]

ABSTRACT: I-CUBE project  has been funded by Inmarsat UK to analyze and evaluate the viability of using Ultra-Narrow-Band (UNB) systems in the return link of LEO constellations. This study has also included the characterization of the satellite channel, the description of the physical layer and the access scheme of a UNB communication system and the [...]

Jordi Serra, Christos Verikoukis, Luis Sanabria-Russo and David Pubill, researchers from the CTTC are awarded for the Best Demo at the IEEE International Workshop on Computer-Aided Modeling Analysis and Design of Communication Links and Networks (IEEE CAMAD 2018).  

ABSTRACT: The development of 5G cellular networks is driven by increasingly diverse requirements, such as 10-fold increase in data rates, few milliseconds latency, and a huge number of connections emerging from the rise of the Internet of Things. This 5G progress is motivating some fundamental changes in the existing architecture of the 4G cellular networks. [...]

In the context of this PhD Thesis defense, Marco Miozzo presents his work realized  at CTTC. This dissertation deals the trend for the next generation of cellular network, the Fifth Generation (5G), predicts a 1000x increase in the capacity demand with respect to 4G, which leads to new infrastructure deployments. To this respect, it is [...]
