The differences and connections between wireless covert communication (WCC) and related concepts were clarified.The WCC research based on hypothesis testing theory and information theory was focused.The basic research model and the categories of specific models were introduced.The existing works were classified and reviewed in two parts, namely, capacity limits and implementation techniques.The former part reviewed the works that reveal the limit rate, and divided them into two categories as per the order of the limit rate: squared root rate and positive rate.The latter part reviewed the works that analyze the performance of WCC systems and optimize the implementation schemes, and classified them as per their application scenarios.Finally, potential research directions were discussed. |
