    Abstract: The disclosure relates to a processing module of a receiver device and associated method and apparatus. The method comprises receiving a signal comprising one or more frames, each frame comprising a synchronization-symbol-portion, a security-sequence-portion, and a data-payload-portion; and processing the signal to perform carrier recovery, and excluding at least part of the security-sequence-portions of the one or more frames from the carrier recovery process.

    Abstract: A processing module for a receiver device. The processor module comprises a channel estimate generation component arranged to output channel estimate information for a received signal, and a timestamping module arranged to determine a ToA measurement for a marker within a packet of the received signal based at least partly on the channel estimate information for the received signal generated by the channel estimate generation component. The channel estimate generation component comprises a validation component arranged to derive a validation pattern for the packet within the received signal for which a ToA measurement is to be determined, identify a section of the packet containing a validation sequence, and perform cross-correlation between at least a part of the validation sequence within the packet and at least a part of the generated validation pattern to generate channel estimate validation information.

    Abstract: An apparatus and method are described for automatically matching the impedance of an antenna. An impedance matching network includes at least one variable impedance element and has an input for receiving a drive signal and an output connectable to an antenna. The impedance matching network includes a shunt capacitor in series between the input and output. A phase measuring measures the phase difference between the voltage and the current of the drive signal using the voltage drop across the shunt capacitor and outputs a measured phase signal. A voltage measuring circuit measures the magnitude of the voltage of the drive signal and the voltage drop across the shunt capacitor and outputs a measured drive voltage signal and shunt capacitor voltage signal. An automatic impedance matching circuit can output a control signal to adjust the impedance of the variable impedance element and determines the impedance of the impedance matching network from the measured phase, drive voltage and shunt capacitor voltages automatically to reduce the difference between the determined impedance of the impedance matching network and the impedance of the antenna.

    Abstract: Embodiments of a multiphase clock generation device may include an input for feeding a reference clock, a clock generation unit adapted to generate phase-shifted clock signals from the reference clock, and a phase comparator unit functionally coupled with the clock generation unit. The phase comparator unit is adapted to measure a phase shift of the phase-shifted clock signals. The multiphase clock generation device includes a self-calibration unit that is functionally coupled with the clock generation unit. The calibration unit outputs a delay-calibration parameter to the clock generation unit. The clock generation unit is adapted to generate a multiphase clock signal out of the reference clock and the delay-calibration parameter.
