摘要：

A new adaptive digital predistortion based on an iterative injections approach is experimentally verified using a 4G signal. An error vector magnitude and spectrum regrowth improvements are achieved, while at the same time not requiring large digital signal processing memory resources and computational complexity. Therefore, the method can be a strong candidate to become a part of modern predistorters for nonlinearity compensation in 4G wireless transmitters.
