| Zusammenfassung: | A METHOD AND APPARATUS FOR IDENTIFYING VALID MULTIPATH ENERGY PEAKS ARE DESCRIBED INCLUDING LOCATING AN ENERGY PEAK IN A PROFILE OF ENERGY PEAKS, CATEGORIZING THE LOCATED ENERGY PEAK BASED ON A PLURALITY OF THRESHOLDS AND PROCESSING ENERGY PEAKS IN AT LEAST ONE OF THE CATEGORIES OF LOCATED ENERGY PEAKS. THE METHOD AND APPARATUS FURTHER INCLUDES REMOVING A DIRECT CURRENT VALUE COMPONENT (405) FROM EACH VALUE IN THE PROFILE OF ENERGY PEAKS, CALCULATING A NOISE FLOOR (410) FOR A MULTIPATH SEARCHING WINDOW AND DETERMINING A FIRST THRESHOLD AND A SECOND THRESHOLD. THE STEP AND MEANS FOR CATEGORIZING FURTHER INCLUDES DETERMINING IF THE LOCATED ENERGY PEAK EXCEEDS THE FIRST THRESHOLD, LABELING THE LOCATED ENERGY PEAK AS A FALSE ALARM, IF THE LOCATED ENERGY PEAK DOES NOT EXCEED THE FIRST THRESHOLD, DETERMINING IF THE LOCATED ENERGY PEAK EXCEEDS THE SECOND THRESHOLD AND LABELING THE LOCATED ENERGY PEAK AS CONFIDENT, IF THE LOCATED ENERGY PEAK EXCEEDS THE SECOND THRESHOLD. |
