The application of MIMO communication systems in real environments will invariably require systems to operate over wideband channels. Although suitable techniques for processing wideband MIMO channels have been reported, their evaluation has mainly been based on simulation using modelled channels. In this paper we investigate some of the properties of wideband MIMO channels and compare the char...

Vehicle-to-vehicle (V2V) communications aim to enhance driver safety and traffic efficiency by using the recently designated frequency bands in the 5.9 GHz range in Europe. Due to the time-frequency selective fading behavior of the vehicular communication channel, multiantenna techniques can provide enhanced link conditions by means of diversity processing. This paper highlights the integration...

Several wireless communication systems are developed for communication needs between train and ground or between trains in the railway or mass transit domains. In order to deploy these systems in specific environments, such as tunnels, straight or curved, rectangular or archshaped section, specific propagation models have to be developed. In this paper, we propose a method to model the radiowav...

This paper purposes an economics analysis of enhanced cooperation in providing European defense public goods. Since 1999, ESDP (European Security and Defense Policy) is implemented with the voluntary agreement of EU members. This kind of (international) public good provision involves theoretically a free-riding problem. To reduce the negative effects related to collective action, we develop a g...

This paper utilizes the Korea Innovation Survey data to find out the determinants of industry-university and industry-GRI (IUG) cooperation and its impact on firm performance. We find first that among determinants of IUG cooperation, traditional firm characteristics variables of sizes and R&D intensity are not significant at all, while the participation at the national R&D project turns out be ...
