| Abstract: |
| The anti-jamming performance of direct sequence spread spectrum(DSSS) TT&C syst
em is
different under different interferences.The differences are discussed. The ant
i-jamming principle and capacity of TT&C sy
stems under different interferences is compared through theoretical analysis and
simulation,and on this base, the suggest
ion of designing a spread spectrum TT&C receiver with anti-jamming ability is g
iven. The study result provids reference for spread spectrum TT&C system design
and anti-jamming testing. |
| Key words: spread spectrum TT&C;processing gain anti-jamming capacity |
