Abstract:
1. A method of operating a wireless receiver, comprising the steps of: receiving a wireless communicated signal, wherein the wireless communicated signal comprises a first synchronization channel component; correlating a synchronization channel value to the wireless communicated signal to produce a plurality of correlation samples in response to a correlation between the synchronization channel value and the wireless communicated signal; comparing the plurality of correlation samples to a threshold; storing as a first set of correlation samples selected ones of the plurality of correlation samples that exceed the threshold and are within a first time sample period and not storing other correlation samples that do not exceed the threshold and are within the first time sample period, wherein each of the correlation samples in the first set has a corresponding sample time relative to the first time sample period; and combining a second set of correlation samples with the first set of correlation samples to form an average sample set and further comprising combining additional sets of correlation samples with the average sample set, wherein each of the additional set of correlation samples has a corresponding sample time; and wherein the combining step comprises combining each sample in each of said additional set of correlation samples with a respective sample in the average sample set such that each combined sample has a like sample time relative to the first time sample period.
