A covert underwater acoustic communication (UAC) method is realized with a dolphin whistle as the information carrier. The proposed method jointly utilizes the spread spectrum and orthogonal frequency division multiplexing (OFDM) techniques. The original dolphin whistle is represented as the complex baseband OFDM transmitted signal and the phase of its

OFDM is a Multicarrier modulation (MCM) technique, which in used in 4G standards. In OFDM systems, symbols are transmitted in parallel on several narrowband subcarriers, which are overlapping and orthogonal to each other. OFDM is superior to other systems because it incurs zero Inter Symbol Interference (ISI) or less amount of ISI which can be ...
