Processor for use as a path searcher of a spread spectrum receiver and a method of operation of the processor |
摘要 |
A path searcher for use in a spread spectrum receiver, including a correlator for correlating a received signal in different time positions with a reference code to select for further processing time positions of the signals showing the strongest correlations, wherein the correlator is operable to obtain a correlation energy result for each time position in a set of possible time positions, a comparator for comparing the correlation energy results with each of a plurality of energy thresholds and a recorder for recording data indicating time positions for correlation energy results which are not less than the respective thresholds in different groups corresponding to the respective thresholds. Also described is a semiconductor device and a receiver incorporating the path searcher and a method of operation of the path searcher. |
