| Abstract: |
| This paper reviewes the development course of Transform Domain Communication Sys
tem(TDCS), introduces basic principle and key technology of TDCS, analyzes its u
nique anti-jammi
ng way, and illustrates the strong anti-interference ability, high spectrum eff
iciency and the Low Probability of Intercept/Low Probability Detect(LPI/
LPD) characteristics of TDCS.It also summarizes the research directions and op
en problems in TDCS area，and finally prospects the good prospect of TDCS, which
points out the direction for further study of TDCS. |
