Patent number: 9967118Abstract: 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: GrantFiled: August 12, 2016Date of Patent: May 8, 2018Assignee: SONY DEUTSCHLAND GmbHInventors: Ralf Böhnke, Seiichi Izumi

Publication number: 20170041177Abstract: 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: October 24, 2016Publication date: February 9, 2017Applicant: Sony Deutschland GmbHInventors: Ralf Bohnke, Thomas DOLLE, Tino PUCH

Patent number: 9438289Abstract: A receiver that receives a reference symbol comprising a sequence of a plurality of synchronization repetition patterns, wherein each repetition pattern contains a predetermined number of samples. The reference symbol is part of a digital signal modulated by using OFDM modulation. An end synchronization repetition pattern in the reference symbol is phase-shifted by 180°, and the phase-shifted synchronization repetition pattern is positioned after the sequence of the number of synchronization repetition patterns. The receiver detects a timing of a correlation peak at the end of said reference symbol by performing a cross-correlation of the synchronization repetition patterns.Type: GrantFiled: November 24, 2014Date of Patent: September 6, 2016Assignee: SONY DEUTSCHLAND GmbHInventors: Ralf Böhnke, Thomas Dölle, Tino Puch

Patent number: 8175109Abstract: The present invention relates to an energy efficient mechanism for establishing and maintaining a communication between nodes (A . . . F) in a wireless communication system. In particular, it relates to a distributed low power medium access control (MAC) mechanism for sharing the communication means in a wireless communication system. According to the present invention a destination node (A) listens to a communication channel periodically. For requesting services from the destination node (A), a wake-up signal (WU) is transmitted from a source node (B) to the destination node (A) via the communication channel, wherein the wake-up signal (WU) is formed by a preamble (WP) and an information for controlling the communication between nodes (A . . . F). The WU signal duration and content is adapted depending on the system operation context to reduce either idle times, power consumption, latency or network blocking (collision avoidance).Type: GrantFiled: November 14, 2005Date of Patent: May 8, 2012Assignee: Sony Deutschland GmbHInventors: Juan Nogueira-Nine, Ralf Böhnke
