By sensing the surrounding electromagnetic environment,TDCS designs the same basic modula-tion waveform at both the receiving and sending devices,which has the property of pseudo-noise and avoids the interference frequency band,thus reducing the probability of signal interception and effectively impro-ving the ability of communication anti-interference.This paper introduces the basic principle of TDCS,re-views the research status of TDCS related technologies,and analyzes the key problems in the current appli-cation of TDCS.
