  • Patent number: 8204072
    Abstract: A method of determining available frequency ranges for at least one communication device is provided. The method comprises providing a downlink transmission time interval, determining available frequency ranges within a plurality of frequency ranges after the downlink transmission time interval, and providing an uplink transmission time interval after the determining of the available frequency ranges.

  • Publication number: 20090286499
    Abstract: A multimode receiver/down converter architecture for use with narrow channel bandwidth and channel bandwidth system signals is described. Interfering signals for a selected narrowband channel are attenuated using a method that reduces the dynamic range of the signal for further processing. The proposed method can be used with a receiver architecture, such as Direct-Conversion, low IF, Super heterodyne, and the like. The downconverted signal is split into two paths. One signal path is delayed and subtracted from the signal from the other path. By controlling the delay value, the interference signals at a given offset are attenuated. Based on the chosen architecture, the desired signal is placed so that the signal undergoes minimal distortion.

  • Publication number: 20090190570
    Abstract: A method of transmitting data from a first communication device to a second communication device is provided. The method comprises transmitting at least one first data portion, transmitting a second data portion synchronized with the transmission of a corresponding data portion of a third communication device to the second communication device, and the transmission of the at least one first data portion being arranged such that it is received by the second communication device before the data portion of the third communication device corresponding to the second data portion.

  • Publication number: 20080207146
    Abstract: The invention relates to an adjustment method, especially for adjusting optical or fibre optical components. Said method involves locally heating, in a defined manner, at least one first partial region of an adjustment region (106, 114) of an actuator (100, 200, 400), in such a way that compressive strains appear in at least one second partial region of the adjustment region of the actuator (100, 200, 400) as a result of the fact that said second partial region prevents the thermal expansion of the heated partial area. When the yielding point ?F of the material of the partial region is achieved, said compressive strains lead to a plastic deformation of the heated partial region. The heated first partial region shrinks during the cooling process, triggering a defined geometry modification of the actuator (100, 200, 400) following the cooling process.
