Overview

Proposed pinching-antenna index modulation enhances spectral efficiency and optimizes transceiver design.

Key Points

  • The proposed PA-IM scheme improves spectral efficiency without added hardware complexity.
  • A comprehensive channel model captures both deterministic and stochastic effects, including path loss.
  • A novel low-complexity box-optimized sphere decoding algorithm is designed for effective signal detection.
  • Simulation results show significant performance gains for the pinching-antenna system over conventional methods.
