Digital Predistortion Utilizing Over-the-Air Feedback for Phased Arrays

Digital Predistortion Utilizing Over-the-Air Feedback for Phased Arrays

In this paper, an efficient digital predistortion (DPD) architecture utilizing over-the-air (OTA) feedback is presented to linearize phased array transmitters. It places one additional observation antenna (OA) in the far field to capture the combined signal of the array outputs and uses the combined...
