Patent ID: 7447257

Claim:
An apparatus for allocating a search resource of a base station modem comprising: a plurality of search controllers for receiving an allocated search resource and searching a multi-path of a radio channel to produce a search result; a plurality of rake receiver for measuring mobility of a terminal based on the search result; and a common search resource allocating unit for adaptively allocating a common search resource to the plurality of search controllers based on a measure of mobility of the terminal, wherein each rake receiver in said plurality of rake receivers comprises a mobility measuring unit for measuring mobility of the terminal, wherein at least one mobility measuring unit measures mobility of a terminal as Lc * W + Rc ⁡ ( 1 - W ) T , wherein Lc indicates number of average level crossings by at least one finger measured for T seconds, Rc indicates number of replaced fingers measured for T seconds, and W indicates weight values of number of level crossings for each finger and number of replaced fingers.
