Overview

Analysis shows improvements in channel estimation accuracy using matched filtering in complex doubly selective channels, suggesting enhanced performance for 6G systems.

Key Points

  • Matched filtering improves channel estimation accuracy in AFDM systems under complex conditions.
  • Signal-to-interference-plus-noise ratio is optimized by addressing inter-chirp-carrier interference effectively.
  • Proposed MF-GFS scheme reduces computational complexity while maintaining performance in wide-band systems.
  • Simulation results confirm significant advancements in communication performance with lower complexity.
