  • System, method and apparatus to reduce error in unused tones in partial bandwidth wireless transmission system
    Patent number: 12652690
    Abstract: In one embodiment, an apparatus includes: a compensation circuit to select one of a plurality of compensation sets based on an allocated resource unit (RU) and compensate a digital complex signal using the selected compensation set; a digital-to-analog converter to convert the compensated digital complex signal to a compensated analog complex signal; a mixer coupled to the digital-to-analog converter to upconvert the compensated analog complex signal to a radio frequency (RF) signal; and a power amplifier coupled to the mixer to amplify the RF signal.
    Type: Grant
    Filed: December 10, 2021
    Date of Patent: June 9, 2026
    Assignee: Silicon Laboratories Inc.
    Inventors: Sriram Mudulodu, Manoj Kumar Medam, Rambabu Katla, Anil Kumar Adavally, Aravinth Kumar Ayyappannair Radhadevi
  • Filtering carrier frequency offset estimations for a device pair combination
    Patent number: 12609717
    Abstract: A receiver includes: an analog front end (AFE) circuit to receive and process an incoming radio frequency (RF) signal comprising a packet; an analog-to-digital converter (ADC) to receive and digitize the processed incoming RF signal into a digital signal; a packet detector to detect the packet; an estimation circuit to determine a carrier frequency offset (CFO) estimate based at least in part on a preamble of the packet; an averager to determine a CFO average value for a plurality of packets communicated between a device pair combination of the receiver and a transmitter; and a compensation circuit to compensate for CFO between the device pair combination based at least in part on the CFO average value.
