MULTI-CARRIER UNDERWATER ACOUSTIC ANTI-INTERFERENCE COMMUNICATION METHOD BASED ON INDEX MODULATION

WIPO Patent Application WO/2022/262172

A1

A multi-carrier underwater acoustic anti-interference communication method based on index modulation. Considering solving the problems of a bit error rate of a receiving end of a system being relatively high due to discontinuous frequency band interference in an underwater acoustic communication environment, etc., on the basis that a one-dimensional sub-carrier state index modulation technique is introduced into a traditional underwater acoustic FBMC communication system, a communication frequency band of an FBMC-IM system is divided according to a discontinuous interference frequency range, such that sub-carriers of a part aliasing with discontinuous frequency band interference signals are silent, and subcarriers which are not interfered with are kept in an active state and bear a communication signal, thereby realizing the division of discontinuous communication frequency bands, avoiding the effect of interference, and improving an anti-interference capability. The method is innovative compared with the existing aspect of interference avoidance for underwater acoustic multi-carrier communications.
