Underwater Acoustic Communication Based on VMCK Modulation

In this paper, ultra narrow band modulation is applied into acoustic communication, which is original and innovative. The Very Minimum Chirp Keying (VMCK) modulation possesses characteristics of an Ultra Narrow Band (UNB) communications. Therefore better spectrum efficiency can be achieved. Experimental results in both air and water demonstrate that the transmission rate can multiply several times of which in conventional modulations, and it is expected to be used in future underwater communication occasions such as submarine.
