摘要
伪卫星(pseudolie)是导航,定位中的一种重要技术,但是对于伪卫星技术一个必须克服的问题就是远近干扰问题,本文研究了利用连续干扰抑制技术抑制远近干扰的伪卫星接收机,提出了抑制远近干扰伪卫星接收机的结构,给出了伪卫星信号重构的关键技术和远近干扰发生的判断原则,并进行了仿真,说明该接收机适合于在伪卫星辅助下的定位应用.
Pseudo-satellites（pseudolie） is a kind of important technique in navigation and positioning,near-far effect is a problem that must be overcomed before using the pseudolie technique,a kind of receiver that can overcome near-far effect by using successive interference cancellation has been studied,the structure of the receiver is given,then the principle of determining the near-far effect and the key techniques of regenerating the pseudolie signal are given.Simulation results indicate that the receiver can be used in positing aided by pseudolie.
