High Concealment Bionic Communication (HCBC) Algorithm based on Wavelet Transform

In this paper, a high concealability bionic communication algorithm is proposed. The algorithm imbedded a confusing signal in each layer of the wavelet, and only the people who communicate with each other know which layer of the wavelet signal contains the target information. The algorithm can enhance the concealability of the signal, but the multi-layer embedding of confusing information will lead to poor bionic performance of the signal. In this paper, an objective function is set up to find the balance between them, and an optimization algorithm is used to solve the objective function. To realize highly concealed bionic communication in complex Marine environment.
