インデックス変調に基づくマルチキャリア水中音響干渉防止通信方法

Japanese Patent JP7455428

B2

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.
