Title: "Exploiting Spatial Modulation & Analog Network Coding for the Design of Energy-Efficient Wireless Networks"
- Speaker: Konstantinos Ntontin, CTTC
- Place: CTTC Auditorium
- Date & Time: 23rd November (Monday) - 10:00h
- Duration: 45 min. (aprox)

An abstract of the presentation follows.

ABSTRACT:

In this seminar, we are going to talk about low-complexity and energy-efficient physical layer-based solutions compared to the already existing approaches, without sacrificing the quality of performance. More specifically, the focus is on the technologies of Spatial Modulation and Analog Network Coding. Both schemes offer the so-called multiplexing gain, which means that multiple streams can be transmitted without sacrificing resources, such as bandwidth.

 

As far as Spatial Modulation is concerned, Spatial Modulation-based schemes are proposed that are more energy efficient than state-of-the-art technologies. Regarding Analog Network Coding, we study its implementation in relay-based scenarios and how it compares in terms of energy efficiency with conventional protocols, such as the time-division multiple access protocol.

 

 

From the obtained results, the conclusion that can be drawn is that depending on the scenario both Spatial Modulation and Analog Network Coding can provide significant energy gains compared to existing technologies without sacrificing performance.



SPEAKER:

Konstantinos Ntontin was born in Athens, Greece, in 1983. He received the Diploma in Electrical and Computer Engineering in 2006, the M. Sc. Degree in Wireless Systems in 2009, and the PhD Degree in 2015 from the University of Patras, Greece, the Royal Institute of Technology (KTH), Stockholm, and the Polytechnic University of Catalonia (UPC), Barcelona, respectively. He joined CTTC in 2011 to conduct his PhD studies. From September 2009 until February 2010, he was a research intern at Ericsson Eurolab GmbH in Aachen, Germany.

 

His research interests are related to the Physical Layer of wireless telecommunications and particularly on topics such as signal processing, MIMO systems, array beamforming, and stochastic modeling of wireless channels.
