A Novel Digital Predistortion Based on Flexible Characteristic Detection for 5G Massive MIMO Transmitters

In this letter, a novel digital predistortion (DPD) technique based on characteristic detection of power amplifiers (PAs) and flexible tuning box is proposed for linearizing large-scale multiple-input-multiple-output (MIMO) system. In this new method, before linearizing the digital block subarray, t...
