Chirp-Based FHSS Receiver with Recursive Symbol Synchronization for Underwater Acoustic Communication

In this paper, we propose a covert underwater acoustic communication method that is robust to fading using a chirp signal combined with a frequency-hopping spread spectrum scheme. A fractional Fourier transform, which estimates the slope of the signal frequency variation, is applied to the receiver...
