Weekly Seminar: “A Sparsity-Perspective to Time-Frequency Signal Representations”

03 August 2015 - 03 August 2015

ABSTRACT: This talk considers nonstationary signal analysis in view of the signal sparsity properties. We examine these signals, which arise in numerous applications, within the framework of compressive sensing (CS) and sparse reconstructions. We present two general approaches to incorporate sparsity into time-frequency signal presentation (TFSR). In the first approach, quadratic TF distributions (QTFDs) are [...]

Weekly Seminar: “When telecommunications networks meet the energy grids: the energy harvesting cellular networks”

15 July 2015 - 15 July 2015

ABSTRACT: The fifth generation (5G) of mobile technology will support 1000 times more capacity per unit area than 4G, for more than 100 billion devices. The higher capacity demanding human-centric communications will be complemented by an enormous increase in the number of communicating machines, the so called Internet of Things (IoT). 5G will enable the [...]

Modelling Heterogeneus Cellular Networks Interference Using Poisson Cluster Processes

08 June 2015 - 08 June 2015

ABSTRACT: Future mobile networks are converging towards heterogeneous multi-tier networks (HetNets), where macro-, pico- and femto-cells are randomly deployed based on user demand. One of the deleterious effects of this set-up is the challenge in accurately modelling the resulting interference. A popular approach for interference modelling is to use stochastic geometry where the location of [...]

Weekly Seminar: “Mobile Data Offloading”

02 June 2015 - 02 June 2015
Speaker: Dr. Jianwei Huang

ABSTRACT: We are witnessing an unprecedented worldwide growth of mobile data traffic. However, traditional network expansion methods by acquiring more spectrum licenses, deploying new macrocells, and upgrading technologies are costly and time-consuming. Clearly, network operators must find novel methods to resolve the mismatch between demand and supply growth, and mobile data offloading appears as one [...]

New waveform designs and the application of FBMC/OQAM to MIMO

27 May 2015 - 27 May 2015

ABSTRACT: The objective of this presentation is to first describe the new waveform designs that are being considered as a potential substitutes of OFDM. The second part is devoted to justify why the filter bank multicarrier modulation based on OQAM (FBMC/OQAM) is identified as one of the most competitive contenders. Finally, the application of FBMC/OQAM [...]

Weekly Seminar: “Radar interferometry: a tool to monitor the dynamic behaviour of civil structures”

ABSTRACT: In the last decade, the monitoring of civil structures has been developed, largely,  thanks to the availability of novel instrumentation based on remote sensing electromagnetic techniques. Although optical devices (mainly Laser vibrometers) have been largely used, radar based techniques also assumed a key role, especially when, due to the large distances, optical observations can [...]

Weekly Seminar: “Introduction to MEMS (Micro Electro Mechanical System)”

29 April 2015 - 29 April 2015
Speaker: Prof. Jung-Mu Kim, Chonbuk National University, Jeonju, Korea

ABSTRACT: Microelectromechanical systems (MEMS) is the technology of very small devices; it merges at the nano-scale into nanoelectromechanical systems (NEMS) and nanotechnology. MEMS are also referred to as micromachines (in Japan), or micro systems technology – MST (in Europe). The fabrication of MEMS evolved from the process technology in semiconductor device fabrication, i.e. the basic [...]

Weekly Seminar: “Enabling LTE and Next Generation 5G Wireless Research with Software Defined Radio”

06 March 2015 - 06 March 2015
Speaker: Erik Luther, SDR Product Group Manager, National Instruments

ABSTRACT: The growing number of wireless devices and scarcity of available spectrum is spurring unprecedented levels of research to design the next generation of wireless systems. Use of software defined radios (SDR) is emerging as a viable way to rapidly prototype custom protocols, analyze performance in real-world environments, and iterate on designs because it closely mirrors [...]

Weekly Seminar: “Satellite Navigation and Galileo: the on-going revolution”

25 February 2015 - 25 February 2015
Speaker: Dr. Javier Ventura-Traveset

ABSTRACT: Satellite Navigation is with no doubt one of the space application sectors with highest growing potential in terms of systems under development, emerging applications and market opportunities. Nowadays, it is estimated that there are over 2 billion satellite navigation receivers worldwide and that this number could exceed 7 billion by 2020. The impact of [...]
