Effects of Residual Chirp Rate on DAFT-s-AFDM Uplink Performance
Henrique L. Senger, Gustavo P. Gonçalves, Bruno S. Chang +2
Affine frequency division multiplexing (AFDM) is robust to doubly dispersive channels in high-mobility 6G systems but, like orthogonal frequency division multiplexing (OFDM), suffe…
Comparative Analysis of Filter Bank Waveforms for ISAC Systems: 2D-FFT FB and AFBM
Polianna Basso, Victor Augusto Del Monego, Hyeon Seok Rou +3
We present a comparative analysis of two promising filter bank multicarrier waveforms for integrated sensing and communications (ISAC) systems operating in high-mobility environmen…
Distortion-Aware Integrated Sensing and Communication with Affine Filter Bank Modulation
Eya Gourar, Henrique L. Senger, Gustavo P. Gonçalves +6
The stringent energy-efficiency requirements of future Integrated Sensing and Communications (ISAC) systems are fundamentally challenged. Unlike conventional communication systems,…
On the Robustness of AFBM Sensing to Power Amplifier Nonlinearities
Eya Gourar, Henrique L. Senger, Gustavo P. Gonçalves +6
We investigate the impact of power amplifier (PA) nonlinearities on the sensing performance of affine filter bank modulation (AFBM). While AFBM offers several advantageous properti…
SIR Analysis for Affine Filter Bank Modulation
Henrique L. Senger, Gustavo P. Gonçalves, Bruno S. Chang +4
The signal-to-interference ratio (SIR) of the Affine Filter Bank Modulation (AFBM) waveform is analyzed under minimum mean square error (MMSE) equalization in two domains; namely,…
