Low-Complexity Memoryless Linearizer for Analog-to-Digital Interfaces

no code implementations12 Apr 2023 Deijany Rodriguez Linares, Håkan Johansson

The paper demonstrates that the proposed linearizer can outperform the conventional parallel memoryless Hammerstein linearizer even when the nonlinearities have been generated through a memoryless polynomial model.
