Two-dimensional memory selective polynomial model for digital predistortion

In this paper, we propose a Two-Dimensional Memory Selective Polynomial (2-D MSP) model for digital predistortion (DPD). The proposed model has been demonstrated to achieve a comparable performance to the well known traditional predistorter models such as generalized memory polynomial (GMP) but with significantly less number of parameters. The proposed model has been validated by evaluating the DPD performance on a class AB power amplifier in terms of adjacent channel power ratio (ACPR).
