  • MEASUREMENT RECEIVER ARCHITECTURE FOR DIGITAL PRE-DISTORTION (DPD) IN MILLIMETER WAVE PHASED ARRAY ENVIRONMENT
    Publication number: 20240235587
    Abstract: Described herein are phased array and transceiver systems with distortion measurement circuitry configured to obtain distortion measurements of system transmitters and provide the distortion measurements to receive beamforming components of the system. Such systems advantageously make use of existing beamforming components of the system to additionally route distortion measurements for baseband DPD processing. Such systems may not need external components to measure signals radiated by antennas of the system or dedicated paths linking system transmitters directly to a baseband processor. In some embodiments, receive beamforming components may be configured to sum distortion measurements from each transmitter to create an aggregate distortion measurement usable as representative of the average transmitter for DPD processing.
    Type: Application
