Publication number: 20150341065Abstract: A transmitting apparatus transmits signals in a digital telecommunication system and a synchronising method is used for synchronizing such signals at a receiving apparatus. The transmitting apparatus prepares for transmission of a reference symbol having at least two repetition patterns, whereby one of the at least two repetition patterns is phase-shifted in relation to the other repetition pattern, and a synchronizing mechanism in the digital telecommunication system uses the reference symbol once received for synchronization. The synchronizing mechanism uses a cross-correlation mechanism to cross-correlate at least one of the two repetition patterns within a correlation window having a predetermined length.Type: ApplicationFiled: August 4, 2015Publication date: November 26, 2015Applicant: Sony Deutschland GmbHInventors: Ralf BOEHNKE, Thomas DOELLE, Tino PUGH

Publication number: 20150110164Abstract: For example in case of an OFDM multicarrier transmission system the transmission characteristics of subcarriers of a multicarrier transmission system using a plurality of antenna elements (3, 3?) can be adjusted. Particularly the power and the phase of the subcarriers can be adapted. To this object the subcarrier frequency channel (2, 2?) characteristics of the multicarrier transmission are detected (11, 11?) at the side of the transmitter (3). The power of each subcarrier is then distributed by a weighting unit (14, 14?). The subcarriers can be further pre-equalized (1, 1?) by dividing the subcarrier signal respectively by the sum of the squared magnitude of the frequency channel characteristics of all subcarrier signals or a frequency characteristic of the selected antenna element (3, 3?).Type: ApplicationFiled: December 30, 2014Publication date: April 23, 2015Applicant: Sony Deutschland GmbHInventors: Ralf BÖHNKE, Seiichi IZUMI
