Publication number: 20210392600Abstract: Examples provide a method for clock calibration. A wireless communication device includes a first clock and a second clock. The first clock is turned off but the second clock runs during the inactive state of the wireless communication device. A frequency offset of the first clock is measured with respect to a reference frequency based on a signal received from a network. A virtual timer, which is a software-based timer is updated based on the frequency offset. A drift of the second clock is measured over a predetermined time interval based on the virtual timer. The virtual timer is restored based on the drift after wake-up from the inactive state. Alternatively, a clock frequency relation between the first clock and the second clock may be measured and a phase locked loop (PLL) may be controlled based on the measured clock frequency relation.Type: ApplicationFiled: December 18, 2017Publication date: December 16, 2021Inventors: Bernd SCHMANDT, Frank HUERTGEN, Michael Mike MEIXNER, Admir BURNIC, Stefan MEYER, Stefan MUELLER-WEINFURTNER, Bernd SCHALLER

Patent number: 7773660Abstract: Frequency channel selection in a data transmission method uses a frequency hopping method. In a first method step, interference in a frequency channel is determined by detecting multiple erroneous transmissions in the frequency channel, and the frequency channel with interference is then eliminated from the frequency hopping sequence. In a second method step, the strength of external signals is measured within the frequency range of an eliminated frequency channel with interference, and the frequency channel is reinserted into the frequency hopping sequence if the strength is below a prescribed threshold value.Type: GrantFiled: March 12, 2004Date of Patent: August 10, 2010Assignee: Infineon Technologies AGInventors: Bernd Schmandt, Frank Gersemsky

Patent number: 7039090Abstract: A method for controlling antennas of a receiving device in a radio system, especially in a mobile radio system, in which at least one change is made using a frequency hopping method between a number of transmission frequencies that are provided for the transmission of radio signals. A table is formed with data relating to the reception quality of each antenna. This data is evaluated on each change to the transmission frequency, and one of the antennas is selected as a function of the result of the evaluation. The method is especially suitable for use in systems using slow frequency hopping methods (slow frequency hopping systems), such as bluetooth or WDCT systems.Type: GrantFiled: May 22, 2002Date of Patent: May 2, 2006Assignee: Infineon Technologies AGInventors: Ulrich Boetzel, Christian Kranz, Bernd Schmandt
