Patent number: 9625565Abstract: A method and an apparatus for determining the position and orientation of a mobile transmitter that has at least two linearly polarized antennas arranged at a predefined angle to one another. A plurality of receivers, which can be synchronized with the mobile transmitter and of which the position is known, each receive transmitter signals of predefined carrier frequency via a circularly polarized antenna. A field-theoretical model of the transmission path between the mobile transmitter and receivers is set up and defines the carrier phase measured values, the field-theoretical model is implemented in a Kalman filter, and the receiver signals are evaluated in terms of carrier phase measured values and/or time of arrival values. The position and orientation of the mobile transmitter are determined in the Kalman filter with use of the field-theoretical model and the carrier phase measured values and/or time of arrival values established from the receiver signals.Type: GrantFiled: July 8, 2011Date of Patent: April 18, 2017Assignees: Friederich-Alexander-Universität Erlangen-Nurnberg, Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.Inventors: Andreas Eidloth, Jörn Thielecke

Patent number: 7120199Abstract: MIMO transmission methods are applied to communicaiton systems in which a transmitter has more than one transmit antenna and a receiver has more than one receive antenna. Information to be transmitted is divided into a plurality of subsignals according to the number of used transmit antennas and each subsignal is processed separately before it is emitted by the respective transmit antenna. In the receiver the different receive signals are processed thus that subsignals are detected and decoded and the contribution of each detected and decoded subsignal is subtracted from the receive signals and whereby a feedback channel from receiver to transmitter is used to send control information to the transmitter depending on the receive situation.Type: GrantFiled: May 3, 2002Date of Patent: October 10, 2006Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jörn Thielecke, Udo Wachsmann
