摘要： A system for diversity processing a signal propagated via two diversity antennas includes: respective propagation paths for propagating two replicas of the signal, these propagation paths being coupled to the two diversity antennas so that the replicas are propagated via different antennas; a time variable delay element for subjecting at least one of the replicas to a time variable delay; and a level adjusting element, such as an asymmetric splitter, to produce a level imbalance between the power levels of the replicas propagated via the two diversity antennas.

摘要： The present invention relates to a method for optimizing the positioning of high sensitivity receiver front-ends 5 in a mobile telephony network 1 of the CDMA type comprising a plurality of cells 2. The method comprises the following steps: defining a first and a second cell indicator Vcell, V2; defining a first and a second threshold value L and L2; comparing said first cell indicator Vcell with a first threshold value L and said second cell indicator V2 with a second threshold value L2; associating with a first category a plurality of first cells 2a having said first cell indicator Vcell greater than said first threshold value L or said second cell indicator V2 greater than said second threshold value L2; positioning a plurality of high sensitivity receiver front-ends 5 substantially in all said plurality of first cells 2a. The method further comprises the steps of: associating with a second category a plurality of second cells 2b having said first cell indicator Vcell smaller than said first threshold value L and said second cell indicator V2 smaller than said second threshold value L2; positioning a plurality of low sensitivity receiver front-ends substantially in all said plurality of second cells 2b.

摘要： In order to reduce the AC losses in a superconducting conductor element subjected to an external magnetic field and through which a current flows, tapes of superconducting material of each layer are wound at such a mutual distance that the gap between the superconducting material of adjacent tapes is not smaller than a predetermined minimum value. These elements are particularly useful in three-phase warm dielectric superconducting cables.

摘要： A system for diversity processing two signals transmitted and/or received via two diversity antennas includes at least four respective propagation paths coupling the signals to the two diversity antennas. Diversity processing is primarily in the form of decorrelation achieved by means of time variable delay elements that apply time variable delays to the signals propagating over at least two of the propagation paths in the system. The related processing may take place either at RF or IF, or at baseband, whereby the time variable delays are applied by subjecting the baseband signals to multiplication by a complex signal.
