| Abstract: | 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. |
