Patent number: 10891248Abstract: A method for communicating between a combo-endpoint device, wireless router and a wireless communication device includes monitoring communication patterns of wireless data communications between a wireless router and radio-communication circuitry of a combo-endpoint device, and storing data indicative of communication times of the wireless router based on the monitored communication patterns. The method further includes configuring a frequency-hopping(FH)-based protocol by defining connection periods according to time windows and selected frequencies for wireless communication of data between the wireless communication device and the radio-communication circuitry, and by establishing the time windows to not substantially conflict with the communication times of the wireless router.Type: GrantFiled: May 15, 2017Date of Patent: January 12, 2021Assignee: NXP B.V.Inventors: Hong Li, Fabian Rivière, Christopher John Gray

Patent number: 10734961Abstract: A receiver includes at least a first amplifier configured to receive a received signal and provide a first amplified signal based thereon, a mixer configured to receive the first amplified signal and provide an intermediate frequency signal based thereon and a second amplifier configured to receive the intermediate frequency signal and provide a second amplified signal based thereon. An automatic gain controller for the receiver is configured to, based on a first overload signal indicative of a first frequency range of the first amplified signal having one or more frequency components exceeding a first maximum signal power threshold and a second overload signal indicative of a second frequency range, narrower than the first, of the second amplified signal having one or more frequency components exceeding a second maximum signal power threshold, provide for control of a respective gain of one or both of the first amplifier and the second amplifier.Type: GrantFiled: September 13, 2018Date of Patent: August 4, 2020Assignee: NXP B.V.Inventors: Sebastien Robert, Fabian Rivière, Franck Bisson, Christophe Olivier Mertens, Samuel Becqué

Patent number: 10581474Abstract: Wireless receivers and related methods with interferer immunity are disclosed. The receiver includes a receive (RX) front-end, a power level detector, and an automatic gain controller (AGC). The RX front-end includes circuit(s) having variable gains, and the power level detector outputs a power level indicator. The AGC receives the power level indicator and outputs the gain settings to the variable-gain circuits within the RX front-end. Further, the AGC is configured to adjust the gain settings within a first gain range when not receiving data frames and to adjust them within a second gain range when receiving data frames. The second gain range is a restricted version of the first gain range. Further, the AGC can be configured to detect and store gain settings within a sliding time window when data frames are not being received and to use these stored gain settings to determine the second gain range.Type: GrantFiled: February 8, 2019Date of Patent: March 3, 2020Assignee: NXP B.V.Inventors: Sebastien Robert, Fabian Riviere, Franck Bisson, Nguyen Trieu Luan Le
