Abstract :
The conventional matched filter structures are investigated in this paper. An acquisition circuit based on the polyphase form matched filter in Global Positioning System (GPS) receiver is provided. At the cost of less hardware resource, the significant advantage in the speed of synchronization is offered. For 32Ã128 polyphase form matched filter, the critical path delay approximately reduces 1/2, the sample frequency would be double.
