Abstract: Disclosed is an underwater acoustic communication system based on a filter bank joint sub-carrier multidimensional index modulation and a method thereof. The system includes a transmitting terminal and a receiving terminal, the method is: conducting a joint index modulation at the transmitting terminal, firstly selecting an activated prototype pulse index by using a part of bits of a FBMC symbol, grouping the remaining transmitted information bits and all sub-carriers; using a part of the bits in each group to select the activated sub-carrier index, modulating the remaining bits to the activated sub-carriers by a constellation symbol mapping, forming a transmission signal after a filter bank modulation; and demodulating three parts of transmitted bits at a receiving terminal after an action of underwater acoustic channel, and recovering the original data bits by combining each part of decoding results.
