  • Patent number: 11894825
    Abstract: This disclosure is directed to filtering in a transceiver of an electronic device. In some instances, active analog filters may be deployed in the transceiver of the electronic device to achieve greater linearity and/or reduce noise in the transceiver. However, as signal bandwidth grows increasingly larger, an active analog filter may consume excessive power. To remedy the excessive power consumption, a passive ladder LC filter may be used. Some LC ladder filters may include a limited quality factor (Q), which may lead to undesirable effects in the transceiver (e.g., voltage droop). To address these undesirable effects, certain components in the LC ladder filter may be relocated from an input port to a feedback chain of an amplifier coupled to the LC ladder filter. The new structure may enable components in the LC ladder filter to be tuned without causing additional voltage droop across the LC ladder filter.

  • Patent number: 11626145
    Abstract: Embodiments of the disclosure include signal processing methods to reduce crosstalk between signal lines of a channel bus using feed forward equalizers (FFEs) configured smear pulse response energy transmitted on signal lines of the channel to reduce pulse edge rates. The coefficients for the FFE may be based on crosstalk interference characteristics. Smearing or spreading pulse response energy across a longer time period using a FFE increases inter-symbol interference (ISI). To counter increased inter-symbol interference caused by smearing pulse response energy, receivers configured to recover symbol data transmitted on the channel bus may each include respective decision-feedback equalizers (DFEs) that are configured to filter ISI from transmitted symbols based on previous symbol decisions of the channel. The combination of the FFE configured to smear pulse responses and the DFE to filter ISI may improve data eye quality for recovery of transmitted data on a channel bus when crosstalk dominates noise.

  • Patent number: 11309927
    Abstract: Radio frequency (RF) communication systems with coexistence management are provided herein. In certain embodiments, a mobile device includes a first antenna, a first front end system that receives an RF receive signal from the first antenna, a first transceiver coupled to the first front end system, a second antenna, a second front end system that provides an RF transmit signal to the second antenna, and a second transceiver coupled to the second front end system. The second front end system observes the RF transmit signal to generate an RF observation signal, which is downconverted and processed by the second transceiver to generate digital observation data that is provided to the first transceiver. The first transceiver downconverts the RF receive signal to baseband, and compensates the baseband receive signal for an amount of RF signal leakage indicated by the digital observation data.

  • Patent number: 10965505
    Abstract: Flexible waveform synthesis is disclosed for new radio (NR) shared spectrum (NR-SS) networks. In order to accommodate variable transmission resources, a transmitter may construct an M×N grid to model a resource element (RE) map of transmission resources available to the transmitter within a shared communication channel, where M corresponds to a number of symbols for a scheduled physical signal and N corresponds to a number of tones of a transmission bandwidth for the transmitter. The transmitter may then map the M×N grid to the RE map and puncture one or more REs associated with the subbands unavailable for transmission in the transmission resources. The transmitter may then transmit a transmission according to the unpunctured REs of the RE map.
