| Abstract: |
| Spread-spectrum Multiple Access system of orthogonal codes is put forward according to the character of aircraft TT&C technology development. The model of transmitter and receiver and the BER performance of system are analysed.The noise performance, multiple access interference and outer interference are simulated.The key techniqnes are discussed, including the acquisition and tracking of orthogonal codes, the ranging technology using PN codes in the system. |
