| Abstract: | Signal acquisition and tracking is a key technology in wireless communications.A signal acquisition and tracking scheme has been designed for spread-spectrum satellite communications,which consists of pseudonoise code acquisition and tracking and carrier acquisition and tracking.Theoretical analysis has been made of the performances of the modules and the scheme verified by using a prototype receiver based on FPGA for its feasibility and robustness. |
