Abstract:
1. A method implemented in a receiver for receiving an incoming signal having data bits spread by a spreading code, comprising: integrating said incoming signal at code phase increments of said spreading code with two or more data bit search patterns in an “A” integration time period comprising at least two non-contiguous “A” time segments for determining magnitudes corresponding to said code phase increments, respectively, for each of said search patterns; integrating said incoming signal at said code phase increments with said search patterns for a “B” integration time period comprising “B” time segments alternating with said “A” time segments for determining magnitudes corresponding to said code phase increments, respectively, for each of said search patterns; and using a largest of said magnitudes for determining a particular one of said code phase increments for receiving said incoming signal.
