Patent ID: 8345810

Claim:
An equalizer based receiver operation method in a mobile communication system, the method comprising: estimating a channel for a multi path receive signal; analyzing a delay profile of a multi path channel; and selecting a tap position from a plurality of tap positions of an equalizer depending on the analyzed delay profile, wherein the selecting of the tap position of the equalizer comprises: comparing a maximum power position with a preset reference position in the analyzed delay profile; selecting a tap position depending on the comparison result; and when the tap position is changed, performing slewing that moves a tap by a predefined amount, and wherein the changing of the position of the tap depending on the comparison result comprises: if the maximum power position and the reference position are substantially identical, determining not to change a position of the tap; if the maximum power position is less than the reference position, determining to change the position of the tap through negative slewing; and if the maximum power position is greater than the reference position, determining to change the position of the tap through positive slewing.
