Receiver Design for Continuous-Time AFDM based on Pre-Filter De-Chirp

Affine frequency division multiplexing (AFDM) is a promising waveform for future high-mobility communications due to its Doppler robustness and diversity gain. However, existing continuous-time AFDM relies on chirp-dependent wideband receive filtering, which increases noise power and causes channel-energy leakage. In t...
