【発明の名称】予備的計算による電力節約型整合フィルタ
Document Type and Number:
Japanese Patent JP2003504909
Kind Code:
A
Abstract:
A technique for correlating a sequence of signal sample values with a predetermined digital code to produce correlation values for shifts in the sequence of signal sample values relative to the predetermined digital code is disclosed. The technique is realized by combining subgroups of the signal sample values in the sequence to form sets of precombinations, and then selecting one precombination from each set of precombinations to provide a plurality of selected precombinations. The plurality of selected precombinations are then added or subtracted to produce a correlation value corresponding to a shift in the sequence of signal sample values.
