摘要
根据飞行器测控技术发展特点,提出多址正交码扩频体制,分析了系统的发射、接收模型及其误码率性能;仿真了多址正交码扩频系统的噪声性能、多址性能和抗干扰性能;讨论了对正交码同步捕获与跟踪、正交扩频体制下的伪码测距等关键技术问题。
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.
