Patent ID: 7079569

Claim:
A search method in a CDMA mobile communication scheme, characterized in that a receiving section which receives a reception signal sent through a radio channel, an analog/digital conversion section which converts the reception signal into a digital baseband signal, a multi-path processing section which includes a plurality of searcher sections and a plurality of finger sections and outputs a plurality of detection signals by processing multi-paths contained in the baseband signal, a RAKE combining section which adds the detection signals to output a combined signal, a signal processing section which processes the combined signal, and a control section which controls the searcher sections are provided, the control section generates a control signal for setting the plurality of searcher sections as two types of function-specific searchers which are a cell searcher and a delay spread searcher on the basis of four signals based on effective path timing information on a delay profile of a reception signal output from the searcher section, effective path energy information of a reception signal processed by the finger section, current reception quality associated with a user and output from the signal processing section, and service quality required for the user and registered in system data, and a control signal is changed to optimally maintain set states of the plurality of searcher sections.
