| Abstract: | The design of the acquisition algorithm of spread-spectrum TT&C signal is presented in this paper.Based on the fast acquisition algorithm of spread-spectrum TT&C signal which is analyzed in detail,the scheme of program is designed,and the solution to the synchronization is given.The processing system of spread-spectrum TT&C signal is implemented in FPGA.The test result proves that the signal can be captured in 0.122 second on the condition of low CNR about 45dB-Hz. |
