Patent ID: 6944207

Claim:
A code division multiple access (CDMA) receiver comprising a searcher for preparing a delay profile in received CDMA signals that indicates a plurality of radio propagation paths to produce path information identifying main propagation paths, said CDMA receiver comprising: path monitoring means for monitoring the path information from said searcher to produce a detection signal when said main propagation paths are stable for a predetermined time interval; and searcher operation controlling means for controlling, in response to said detection signal, said searcher to make said searcher intermittently operate at a predetermined intermittent period, wherein said path monitoring means includes: path information memory means for storing current path information from said searcher as stored path information; path comparing means for comparing said stored path information with said current path information, said path comparing means producing a path coincidence signal when said stored path information coincides with the current path information; and path coincidence counting means for counting, in response to said path coincidence signal, a path coincidence count, said monitoring means producing said detection signal when said path coincidence count reaches a predetermined count.
