Claims
- 1. A method of acquiring a received signal in a spread-spectrum system, the method comprising:separating the received signal into component channel signals; selecting a number of the component channel signals to search; selecting a number of frequency bins to search from a plurality of frequency bins; generating a plurality of pseudo-noise (PN) signals; pairing a selected component channel signal with a selected frequency bin and a generated PN signal thereby generating a signal pair; and searching the signal pair for the received signal.
- 2. The method of claim 1 wherein the received signal is a single channel signal.
- 3. The method of claim 1 wherein the received signal is a multi-channel signal.
- 4. The method of claim 3 wherein the selected number of component channels to search is one.
- 5. The method of claim 3 wherein the selected number of component channels to search is two.
- 6. The method of claim 3 wherein the selected number of component channels to search is three.
- 7. The method of claim 1 wherein the selected number of frequency bins to search is one.
- 8. The method of claim 1 wherein the selected number of frequency bins to search is two.
- 9. The method of claim 1 wherein the plurality of generated PN signals are identical.
- 10. The method of claim 1, wherein the received signal is a multi-channel signal with each channel of the multi-channel signal containing signal energy, further comprising selective posterior energy combining of the signal energy of the channels of the multi-channel signal.
- 11. The method of claim 1, further comprising generating and searching additional signal pairs and compiling a peak list based on the searching of the signal pairs.
- 12. The method of claim 1, further comprising generating and searching additional signal pairs and compiling a plurality of peak lists based on the searching of the signal pairs.
- 13. The method of claim 1 wherein the spread-spectrum system is a code division multiple access system.
- 14. The method of claim 1 wherein the received signal is a pilot signal.
- 15. The method of claim 1 wherein the received signal is a multichannel pilot signal.
- 16. The method of claim 1 wherein the received signal is a global position system signal.
