Patent number: 7378921Abstract: The present invention provides a coupling arrangement for coupling out a RF signal of a transmission line connecting a first and a second RF unit, such like an IQ modulator and a power amplifier. The coupling arrangement comprises first and second coupling means that are adapted to be coupled to respective first and second transmission lines connecting the RF units. The first and second transmission lines separately provide transmission of respective first and second RF signals forming a differential RF signal. Preferably, the first coupling means are adapted to provide coupling out of the first RF signal, thereby inevitably affecting transmission of the first RF signal. The second coupling means provide a substantially equal impact on the transmission of the second RF signal, such that the net impact of first and second coupling means on the differential RF signal nearly vanishes.Type: GrantFiled: July 6, 2005Date of Patent: May 27, 2008Assignee: Evolium S.A.S.Inventor: Rainer Ziegler

Patent number: 7330458Abstract: A method and system for synchronizing terrestrial nodes equipped with GNSS (Global Navigation Satellite System) receiver belong to a terrestrial network. Synchronization is achieved by selecting terrestrial node to be synchronized to form a synchronization zone. The clear sky view solid angle shared by the terrestrial nodes is determined. The terrestrial nodes acquire a rough time reference sent by a satellite that can be viewed by the terrestrial nodes in the clear sky view solid angle. A common synchronization date is determined for all the terrestrial nodes. And, at the common synchronization date all the terrestrial nodes acquires a predefined sequence from the satellite. The terrestrial nodes uses this sequence to adjust the reference time.Type: GrantFiled: September 10, 2002Date of Patent: February 12, 2008Assignee: Evolium S.A.S.Inventors: Antoine Soulie, Pierre Dupuy

Patent number: 7292836Abstract: The invention relates to a direct conversion receiver for down-converting a received multi-carrier signal comprising at least a first and a second carrier signal at image carrier frequencies to a base band resulting in that the first carrier signal includes an image signal of said second carrier signal. Further, the known direct conversion receiver comprises at least a first and a second digital down-converter unit for separating the first and the second carrier signal from the down-converted multi-carrier signal after digitization. In order to make such receivers less complex and adjust them for fast time varying szenarios it is proposed to provide an error estimating unit to said receivers for calculating a compensating coefficient representing the quota and/or the phase position of the image signal of the second carrier signal being included in the first carrier signal and to remove the undesired image signal in response to said compensating coefficient.Type: GrantFiled: November 6, 2003Date of Patent: November 6, 2007Assignee: Evolium S.A.S.Inventors: Friedrich Endress, Luc Dartois
