Adaptive Modulation Tracking for High-Precision Time-Delay Estimation in Multipath HF Channels
High-frequency (HF) communication is critical for applications such as over-the-horizon positioning and ionospheric detection. However, precise time-delay estimation in complex HF channels faces significant challenges from multipath fading, Doppler shifts, and noise. This paper proposes a Modulation...
