The Research on the Digital Short Radio Covert Communication Based on Audio Signal Information Hiding Technology

The covert communication technology based on information hiding is the important applied region of information hiding science, which owes special important meaning to the development of military and other special communication. The short radio covert communication precedes traditional communication technology in many aspects, such as the width of cover and steady signal, strong fight crushing, cheapness, lightness, high dependability and so on. Due to the research meaning and the realistic demand of the short radio covert communication based on information hiding technology, a new method of the digital short radio covert communication based on audio signal information hiding is proposed in this paper, which offers an approach to realize middle and long sized-distance broadcasting communication, settle the problem of frequency congestion, raise the safety and dependability of covert communication and realize wireless telecommunication minimally.
