Spectrum Aggregation and Multi-User MIMO: Real-world Impact (SAMURAI)
Date du début: 1 janv. 2010, Date de fin: 31 oct. 2012,
Next generation cellular wireless systems will require data rates which are one order of magnitude higher than the ones provided by current systems.One way to improve the rates is to increase the bandwidth. Unfortunately, spectrum is a fragmented resource and large bands of frequencies are unavailable to one single operator. Therefore, Spectrum Aggregation (SA) represents an opportunity to overcom ...

Ultra-wide band real-time interference monitoring and CELLular management Strategies (UCELLS)
Date du début: 1 janv. 2008, Date de fin: 31 déc. 2010,
Ultra-Wide Band (UWB) is a wireless technology which exhibits unique features such as spectrum coexistence with other wireless services, RF front-end simplicity (enabling potential low cost terminals), good radio wave propagation (robustness against multi-path fading, material penetration) and high bitrate. Current UWB implementations target short-range ultra-high bitrate point-to-point wireless c ...

Physical layer for dynamic spectrum access and cognitive radio (PHYDYAS)
Date du début: 1 janv. 2008, Date de fin: 31 oct. 2010,
PHYDYAS proposes an advanced physical layer, using filter bank-based multicarrier (FBMC) transmission, for the new concepts in radiocommunications: dynamic access spectrum management (DASM) and cognitive radio. It shows that the performance and operational flexibility of systems are enhanced by exploiting the spectral efficiency of filter banks and the independence of sub-channels. Combining wit ...

MOdelling and CHAracterization for SiP Signal and Power Integrity Analysis (MOCHA)
Date du début: 1 janv. 2008, Date de fin: 31 mars 2010,
Today advanced System-in-Package(SiP) can integrate several Large-Scale-Integration(LSI) technologies and functionalities (advanced System-on-Chip-SoC),high-density memories,high-performance analogue-block.It's become strategic to analize and detect potential signal and power integrity failures before the prototype phase.The key to success is a set of integrated EDA tools and modelling flows that ...
