Abstract
A method for mitigating interference in a receiver, where the received signal is transmitted in a fashion having equivalent information content in at least two distinct bands. The method compares mean power per unit bandwidth in suitably normalised sidebands and sets a rejection threshold based upon the measured levels. Bands above the threshold may be rejected from further processing. The bands may include sidebands produced by a modulation process that produces sidebands having the same informational content. The threshold may be set relative to the band having the lowest mean power per unit bandwidth or according to some other function of the bands. Also extends to a signal processor in a receiver, and a receiver. The primary focus of the application is toward the Galileo Public Regulated Service (PRS) Satellite navigation signal.

Full Text
- (A) 2.0 to 8.0 mol % of vinylidene fluoride,(B) 60.0 to 70.0 mol % of tetrafluoroethylene,(C) 35.0 to 25.0 mol % of perfluoro(lower alkyl vinyl ether) or perfluoro(lower alkoxy-lower alkyl vinyl ether), and(D) 0.2 to 3.0 mol % of a perfluoro unsaturated nitrile compound, and having a Mooney viscosity ML1+10(121° C.) of 65 to 110, as well as a vulcanizable fluorine-containing elastomer composition comprising said fluorine-containing elastomer and a bisamidoxime compound in an amount of 0.2 to 5 parts by weight based on 100 parts by weight of the fluorine-containing elastomer. A sealing material obtained by vulcanization-molding of the fluorine-containing elastomer has not only excellent compression set characteristics and plasma resistance, but also low adhesion to metal at a higher temperature, specifically 150° C.
