Can I read LUT-Based LNA Distortion Compensation on EtoBox?
LUT-Based LNA Distortion Compensation by Vu Ngoc Anh is a document available to read on EtoBox.
What is LUT-Based LNA Distortion Compensation about?
The document presents a novel LUT-based linearization scheme to compensate for nonlinear distortion effects of Low Noise Amplifiers (LNA) in Direct-Sampling Receivers (DRF). It describes the training process using an internally-generated signal to estimate LNA nonlinearity, which is then stored in a LUT for distortion removal during signal reception. Simulation results demonstrate significant improvements in amplification linearity, with a notable increase in Adjacent Channel Power Ratio (ACPR).
