A novel and improved method of acquisition in a spread spectrum communication system is presented. In the present invention, a large window of PN chip offset hypotheses are searched and if an energy signal is found that might indicate the presence of the pilot signal having one of the chip offsets of the large search window, then a search of a subset of offset hypotheses, or small window, is searched.

[ I claim:] [1.] A method for determining a synchronized PN sequence, comprising the steps of:demodulating a received signal by a first plurality of PN sequences of a first set of windows of PN sequences determined in accordance with a first window parameter format to provide a first set of demodulation metrics;analyzing said first set of demodulation metrics to determine whether said synchronized PN sequence is of said first plurality of PN sequences; anddemodulating said received signal by a second plurality of PN sequences of a second set of windows of PN sequences determined in accordance with a second window parameter format to provide a second set of demodulation metrics;wherein said first window parameter format further comprises a number of passes for verification.
