METHOD AND APPARATUS FOR DETECTING SIGNAL PROPAGATION TYPE

摘要

The present invention relates to a method and apparatus for detecting the type of signal propagation, the method comprising: calculating a plurality of similarity values when a location base station in an ultra-wideband location system currently receives a pulse response from a location tag, wherein each of the similarity values represents the degree of similarity between the currently received pulse response and one of a plurality of reference pulse responses, and the plurality of reference pulse responses are pulse responses from at least one location tag that were previously received by the location base station where the type of signal propagation between the location base station and the at least one location tag is a specific type of signal propagation; and determining, based on the plurality of similarity values, a current type of signal propagation between the location base station and the location tag. The method and apparatus can be used to detect the type of signal propagation between the location base station and the location tag in the UWB location system.
