  • Patent number: 11561601
    Abstract: A system and method for efficiently transferring data between devices. In various embodiments, a host computing device receives parallel data, encodes the parallel data as a count of pulses as serial data, and conveys the serial data to a peripheral device. The peripheral device decodes the received serial data to determine the parallel data, which is sent to processing logic. The devices send the encoded pluses on a bidirectional line, so the pulses are capable of being sent in both directions. The devices send the encoded pulses on the bidirectional line using a non-zero base voltage level. The devices are capable of using a voltage headroom when conveying encoded pulses between one another. Therefore, a full voltage swing between a ground reference voltage level and a power supply voltage level is not used when conveying the encoded pulses, which reduces power consumption.

  • Patent number: 11224014
    Abstract: Power management for remote units in a wireless distribution system. Power can be managed for a remote unit configured to power modules and devices that may require more power to operate than power available to the remote unit. For example, the remote unit may be configured to include power-consuming remote unit modules to provide communication services. As another example, the remote unit may be configured to provide power through powered ports in the remote unit to power-consuming devices. Depending on the configuration of the remote unit, the power-consuming remote unit modules and/or power-consuming devices may demand more power than is available at the remote unit. In this instance, the power available at the remote unit can be distributed to the power-consuming modules and devices based on the priority of services desired to be provided by the remote unit.

  • Patent number: 11038544
    Abstract: Aspects include an apparatus and a method for performing Second Order Input Intercept Point (IIP2) calibration of a Digital-to-Analog (DAC) during a full-duplex mode receive operation. In some aspects, a plurality of correlation values are obtained, indicating an amount of IMD energy of an RF signal, wherein the correlation values are associated with IIP2DAC values of a DAC. In some aspects, the apparatus can calculate a mixer bias value, based on the correlation values, and adjust a bias value of a mixer according to the determined bias value. The apparatus can obtain the correlation values, calculate the bias value, and adjust the bias value of the mixer during the full-duplex mode receive operation. In some aspects, the apparatus can thus improve IIP2 of the mixer and reduce IMD energy in a receive signal, during the receive operation, without the need of standby or factory calibration.

  • Patent number: 10845401
    Abstract: Nonlinear distortion of a device under test (DUT) is detected by obtaining measurements of a multi-tone input signal from a signal generator to a DUT, to obtain a measured multi-tone input signal. Measurements are also obtained of a multi-tone output signal from the DUT that is generated based on the multi-tone input signal, to obtain a measured multi-tone output signal. A correlated part of the measured multi-tone output signal that is correlated with the measured multi-tone input signal is determined insofar as the correlated part corresponds to a frequency response function of the DUT.

  • Patent number: 10694451
    Abstract: Methods and systems are described for determining an optimal access point for a client device based on the relative difference between signal strengths of wireless signals received by the client device from access points. In particular, the signal strengths of wireless signals received by a client device from access points are determined without receipt of signal strength and/or transmit power information from the client device. Instead, the signal strength difference value may be determined based on known characteristics of signals transmitted by the access points and known characteristics of signals received by the access points from the client device. This relative difference value may thereafter be used to determine an appropriate access point to provide network access to the client device.
