Abstract
A spreading signal acquisition and tracking method and apparatus is proposed. In accordance with the present invention, coherent integrations are performed by segments and stored for a non-coherent integration. A better freedom of the non-coherent interval selection is provided. The window of the non-coherent integration is sequentially and gradually shifted to achieve better update rate to its detection circuit and to improve searching and tracking for a spreading signal. By using the present invention, rapid signal acquisition can be achieved even when intensity of the spreading signal is very weak, or even when deeper signal blocking or jamming occurs.
