European Cooperation in the Field of Scientific and Technical Research
The relative permittivity of LCP material has been characterized within the whole 60 GHz frequency band using the microstrip ring resonator (MRR) method. Using a circuit model, the gap capacitance of the MRR has been taken into account in order to improve the accuracy of the determined relative permittivity. The results show that the relative permittivity of LCP is almost constant (εr ≈ 3.1) wi...

To dimension cellular wireless networks, accurate estimates of the cell throughput have to be available. Consideration of all requirements of future packet-switched networks, especially the impact of scheduling, leads to extensive system level simulations that have to be performed in order to obtain the cell throughput. A semi-analytical methodology is proposed in this paper that is able to giv...

This paper proposes simplified antenna model and a position estimating approximation for a system level simulation of advanced handover protocols with smart antennas. This models have been implemented in our simulation tool MOSIT that is based on the Specification and Description Language SDL (ITU Z.100). One application of our simulation tool is the examination of a new approach for a advanced...

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...
