Abstract :
This paper describes the principle of TT&C system based on DS (Direct Sequence)/FH (Frequency Hopping) hybrid spread spectrum technique. An implementation scheme for its base band signal processing is designed. A fast acquisition scheme for DS/FH hybrid spread spectrum signal under the condition of Doppler frequency shift is put forward in and a hardware platform which verifies the base band signal processing of the TT&C system proposed in this paper is built.
