Abstract :
A new acquisition scheme is proposed after its basic conception being introduced. The new algorithm is mainly about PN synchronization and symbol synchronization. To realize PN synchronization, a way based on chip-level difference is adopted. For the implementation of symbol synchronization, a new algorithm on basis of post-correlation filtering and peak detecting is presented. It is shown from the simulations that the scheme can be implemented well and the performance is excellent.
