CAPTIV is a research program proposing new low-cost and energy-efficient mobile communications solutions to ease and make safer road traffic conditions. Considering ??intelligent?? road signs and vehicles, i.e. equipped with an autonomous radio communication system, drivers will be able to receive at any time various information about traffic fluidity or road sign identification. In order to reduce...
This paper presents the realization of the digital block of a hardware simulator of MIMO propagation channels for UMTS and WLAN applications. The hardware simulator must reproduce the behavior of the radio propagation channel, thus making it possible to test "on table" the mobile radio equipments. The advantages are: low cost, short test duration, possibility to ensure the same test conditions...
The aim of the French regional research project SIMPAA2, which continues the former national research SIMPAA project, is the realization of a hardware simulator of MIMO propagation channels for UMTS and WLAN applications. The simulator must reproduce the behavior of the radio propagation channel, thus making it possible to test "on table" the mobile radio equipments. The advantages are:...
In this paper, we present the design and calibration of two antenna arrays, of 4 active elements each, at 3.5 GHz for double directional channel measurements. This frequency band is used for wireless local loop (WLL) applications. The beam patterns of these two arrays are measured in anechoic chamber. A calibration algorithm is applied on these measurements for high resolution 4times4 MIMO (multiple...
