    摘要： Methods and apparatus for conditioning communications signals based on detection of high-frequency in the polar domain. High-frequency events detected in a phase-difference component of a complex baseband signal in the polar domain are detected and used as a basis for performing hole-blowing on the complex baseband signal in the quadrature domain and/or nonlinear filtering either or both the magnitude and phase-difference components in the polar domain. Alternatively, high-frequency events detected in the phase-difference signal that correlate in time with low-magnitude events detected in a magnitude component of the complex baseband signal are used as a basis for performing hole-blowing on the complex baseband signal in the quadrature domain and/or nonlinear filtering either or both the magnitude and phase-difference components in the polar domain.

    摘要： A technique of processing an input signal having an input signal phase is disclosed. The technique includes determining a number of transitions of the input signal within a period having a start and an end. The technique includes determining a relative beginning phase of the input signal at the start of the period, which includes generating a first reference signal having a first reference signal frequency and a first reference signal phase synchronized with the start of the period, and detecting a first time interval required for the input signal phase to have a first specified relationship to the first reference signal phase. The technique includes similarly determining a relative ending phase of the input signal at the end of the period. The technique includes determining an input signal temporal characteristic from the number of transitions and the relative beginning phase and the relative ending phase.

    摘要： A simulacrum security device and methods. In one embodiment, a simulacrum or likeness of a physical security device is provided for use in conjunction with a software emulation of the security device. In one implementation, a “faux SIM card” is provided that does not contain Subscriber Identification Module (SIM) information itself, but instead enables a user to download Electronic SIM (eSIM) information (e.g., from a network or eSIM server) which is loaded into a software emulation of a Universal Integrated Circuit Card (UICC) device. The faux card is printed with an activation code, scan pattern, or other activation or access information. The subscriber purchases the faux card, and enters the activation code into a device; the entered activation code enables the device to log onto a network, and download the appropriate eSIM data. Delivery of eSIM information as enabled by the faux card addresses deficiencies in existing SIM distribution schemes, provides users with an enhanced perception of security, and further addresses various legal requirements.

    摘要： Transmitters, receivers and associated methods are disclosed for providing phase and amplitude modulation in a carrier-less communication system (e.g., an ultra-wide band communication system). An approximate quadrature signal is provided by delaying the in-phase signal by an amount determined by various criteria, such as the bandwidths of the component signals, minimizing the mean square error between an approximate quadrature signal and the true quadrature signal, and minimizing the auto-correlation function of the in-phase signal.

    摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communications circuitry may include microelectromechanical systems (MEMS) switches that receive radio-frequency antenna signals from antennas. The wireless communications circuitry may include switching circuitry interposed between the MEMS switches and the antennas. The switching circuitry may protect the MEMS switches from radio-frequency signals that are received by the antennas by temporarily isolating the MEMS switches from the radio-frequency signals during MEMS switch configuration processes. The switching circuitry may include a crossbar switch formed from solid state circuitry. The wireless communications circuitry may include control circuitry that controls the MEMS switches and the switching circuitry. The control circuitry may direct the switching circuitry to temporarily disconnect a selected MEMS switch from the antennas and direct the selected MEMS switch to switch from a first configuration to a second configuration while the MEMS switch is disconnected from the antennas.
