【 摘 要 】

References(12)The memory polynomial (MP) model is a frequently used structure for digital predistortion (DPD) of power amplifiers (PAs) in wireless communication systems, but it has limited performance. In this paper, we propose a compound memory polynomial (CMP) model to enhance the accuracy. The CMP model is constructed by adding the terms concerning the difference of the input to the MP model. The effectiveness of the CMP model is demonstrated experimentally.
