  • Patent number: 9225558
    Abstract: 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.

  • Publication number: 20150341065
    Abstract: 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.

  • Patent number: 9184963
    Abstract: 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.

  • Publication number: 20150110164
    Abstract: 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?).

  • Patent number: 8892058
    Abstract: A communication system including a first station having at least two first narrow beam antennas and a second station having at least two second narrow beam antennas. The first and second stations establish a first communication path for wireless communication via a pair of first and second narrow beam antennas. When communication via the first communication path is disturbed by obstacles, the first and second stations automatically establish at least one alternative communication path, which is spatially different from the first communication path, for wireless communication using the at least two first narrow beam antennas and the at least two second narrow beam antennas.

  • Patent number: RE45269
    Abstract: In an OFDM transmission a transmission diversity technique is used without orthogonal signaling. The phases of the subcarriers received at the different antennas are compared by different techniques and then the phases of the signals for different antennas are adjusted for a subsequent transmission over the OFDM interface. The phase (and optionally amplitude) adjustment is calculated in only one (transmitting) side and no orthogonal signaling required. The number of antennas can be increased as much as necessary to get a sharper beam. The negative effects of fading and interference can be reduced so that at same time a down link transmission power can be reduced.
