Title: Apparatus for searching multipath in spread spectrum cummunicatios and method thereof
Inventor: EO IK SU
IPC: H04B1/7117
Filed: 2001-11-30
Abstract: PURPOSE: A device for searching a multi-path of a spread spectrum communication system and a method thereof are provided to search each time delay information for signals having a short delay time about 1 chip, and to assign the information to a rake receiver, thereby improving efficiency of a receiver. CONSTITUTION: A radio receiver(300) converts received radio signals into baseband signals, and outputs the converted signals. A profile calculator(311) calculates a multi-path profile of the baseband signals, and outputs a calculated result. The first detector(315) compares a peak value of the multi-path profile with a value of a profile distant from the peak by a predetermined time, to decide whether the radio signals pass a short delay multi-path. A path selector(313) receives the multi-path profile and a detection result of the first detector(315), to generate time delay information by paths and separate plural paths where the radio signals passes. And a receiving unit(330) receives the time delay information of the paths and despreads the baseband signals to sum the despreaded signals.
