A REPEATER FOR ELIMINATING MULTI-PN IN MOBILE NETWORK SYSTEM AND METHOD THEREOF

摘要

A repeater for eliminating multi-PN(pseudo noise) in a mobile network system and a method thereof are provided to improve the efficiency of a repeater by removing the multi-PN measured from the wireless signal, and to promote a mobile service reliability by means of an outdoor high power service, and to improve the receiver capacity. A repeater amplifies and transmits a wireless signal. A multi-PN detection part(350) detects multi-PN by using the wireless signal - the wireless signal includes the plural base station(multi-base station) signal - received through an antenna. A multi-PN elimination part(360) eliminates the pilot signal of the multi-base station corresponding to the multi-PN signal from the wireless signal by using multi-PN signal. A feedback signal elimination part(340) detects and eliminates the feedback signal from the wireless signal, incase of including the feedback signal - the signal re-entered through the receiving antenna after being transmitted from the repeater - in the wireless signal. A feedback signal detector(341) estimates the time retardation, amplitude and phase of the feedback signal by using correlation of the wireless signal.
