Overview

This analysis uncovers time-scaling effects in doubly-dispersive channels, optimizing AFDM transmission performance.

Key Points

  • The study derives input-output relationships for AFDM systems over time-scaled wideband doubly-dispersive channels.
  • An efficient transmission structure with chirp-periodic prefixes and suffixes is developed for enhanced performance.
  • The CD-D-OAMP detection algorithm is proposed to balance complexity and performance while achieving faster computation.
  • Results show optimized chirp parameters provide significant advantages over existing modulation schemes in specific channel conditions.
