Patent number: 9225558Abstract: A method for receiving a signal, which is transmitted over a pair of wires is measuring a differential mode (DM) signal and is measuring a common mode (DM) signal and using both DM and CM to restore the original signal. A corresponding receiver (1) comprises a CM receiving path (3), a DM receiving path (2) and a digital signal processor (22) to combine CM and DM signals. With this method and receiver (1) the coverage of networks, which are slightly unbalanced, can be enhanced, especially in cases where the CM signal is less attenuated than the DM signal.Type: GrantFiled: March 1, 2007Date of Patent: December 29, 2015Assignee: SONY Deutschland GmbHInventors: Andreas Schwager, Stephen Tiedemann, Dietmar Schill

Patent number: 9184963Abstract: A transmitting device, a receiving device, and a communication method for transmitting and receiving data modulated on frequency subcarriers of an OFDM communication system. An OFDM burst includes a preamble part and payload data part, whereby the preamble includes a section of pilot symbols mapped onto every n-th frequency subcarrier and signaling data mapped onto the frequency subcarriers between the frequency subcarriers with the pilot symbols. A first channel estimation on the basis of the received pilot symbols is performed, the result of which is used to reconstruct the entire section of the received preamble as a training pattern for an accurate channel estimation, which is used for a channel equalization of the received payload part.Type: GrantFiled: September 9, 2014Date of Patent: November 10, 2015Assignee: SONY DEUTSCHLAND GmbHInventors: Lothar Stadelmeier, Markus Zumkeller, Andreas Schwager, Stephen Tiedemann, Gralf Gaedeken

Patent number: 8576053Abstract: Near field communication (NFC) device including a processor and a front end unit (FEU) to communicate with an external reader/writer device. The FEU stores, by first memory, a first number of sets of application parameters, each set including first and second identifiers. The processor stores, by second memory, the application and a second number of the sets. The FEU receives a communication request from the external device, including a certain first identifier. The FEU checks, when the request is received, whether the certain first identifier is stored in the first memory. If yes, a response is sent to the external device, including a respective second identifier, which is in the same set of parameters as the certain first identifier. The FEU sends, each time a request is received, a response to the processor. The processor controls which sets of parameters are stored in the first memory based on the response.Type: GrantFiled: September 22, 2011Date of Patent: November 5, 2013Assignee: Sony CorporationInventors: Meik Buscemi, Stephen Tiedemann, Frank Dawidowsky, Klaus Röhrle, Dietmar Schill
