FAST ACQUISITION, HIGH SENSITIVITY GPS RECEIVER |
摘要 |
A method and apparatus of acquiring and tracking global positioning system signals with fast acquisition speed and high sensitivity is disclosed. A pseudo-random noise matching filter operation is performed on a sample of global positioning system signals to provide a current matched filter result. The current matched filter result is then accumulated with a prior matched filter result from a prior sample of global positioning system signals to produce an accumulated matched filter result. Efficient means for implementing the matched filter are disclosed.
