A Dual-band Sample Selection Method for 2-Dimension Digital Predistortion

In this paper, a dual-band sample selection method (DB-SSM) for 2-dimension digital-predistortion (2-D-DPD) was presented. The characteristic of dual-band modeling is considered and a simple association form between the amplitudes of dual-band signals is determined. Since only one sample selection process needs to be performed, no additional complexity is added. The experimental results show that the proposed method can achieve a better trade-off between linearization performance and complexity.
