Abstract

This paper demonstrates digital predistortion (DPD) scheme employing two-dimensional vector-piecewise-decomposition (2D-VPD) on concurrent noncontiguous signals. Simulation results show piecewise predistorter achieves noise floor of -60dBc, an on-par performance with 4 nonlinearity order terms compared to 7 on non-piecewise predistorter. Optimal selection of the piecewise decomposition improves predistortion residual floor by 10dB. The suggested predistorter enables complexity reduction on both learning and implementation, which result in cost and power efficient design for WiFi, mobile and IoT solutions.
