Bio-Mimetic Underwater Covert Communication Technique Using Modified Least Significant Bit

초록

This paper proposes an underwater acoustic communication technique by mimicking a dolphin whistle based on modified LSB Steganography. The performance of the proposed technique is evaluated through simulations and experiments in the Yellow sea in terms of bit error rate, and compared with conventional chirp spread spectrum (CSS) technique. The degree of mimic is also compared by observing spectral correlation and MOS Test. © 2020, Korean Institute of Communications and Information Sciences. All rights reserved.
