Patent ID: 7075974

Claim:
A method of detecting a peak from delay profile data received through a multi-path in a CDMA receiver, comprising the steps of: dividing the delay profile data into a plurality of data blocks; searching a maximum value of the delay profile data at every data block; and storing each maximum value at every data block to detect the peak from the maximum values searched from the respective data blocks subsequently detecting a following peak after the peak is previously detected as a previous peak using said stored maximum values; wherein the subsequently detecting step further comprises the steps of: masking a neighboring time region of the delay profile data adjacent to the previous peak to obtain renewed delay profile data; determining, from the renewed delay profile data, a specific one of the data blocks that includes the previous peak; and judging whether or not the previous peak is located on a right-hand side of a center of the specific data block to produce a result of judgement; and re-executing the searching step also about either of a right-hand side data block and a left-hand side data block adjacent to the specific data block with reference to the result of judgement along with the specific data block.
