Two-Stage IQ Imbalance Estimation and Compensation for AFDM Systems
Zhenfeng Huang, Yitong Liu, Yuping Yan +1
Affine frequency division multiplexing (AFDM) is an emerging chirp-based multicarrier waveform with strong diversity in doubly selective channels, but practical systems suffer from…

Performance Analysis of AFDM Under In-Phase and Quadrature Imbalance at Receiver
Zhenfeng Huang, Yitong Liu, Hongwen Yang
Affine Frequency Division Multiplexing (AFDM) is a chirp-based multicarrier waveform that achieves full diversity in doubly selective channels while requiring reduced pilot overhea…
