Assessment of delay estimation quality using interference estimates

It is related with the method and system which determine the time of an additional multipass ingredient being not being contained in RAKE processing, and it is new or can be used in a channel. According to some enforcement forms, the present invention uses an interference point estimate about all the RAKE fingers relevant to the multipass ingredient under pursuit, and determines a part of signal energy which was caught by the path searcher at present and which can be exploited. When a part of electric power which was caught with the path under pursuit and which can be used is less than a predetermined threshold value, the present invention starts a path searcher and makes an additional multipass ingredient search.
