BASE STATION, RECEIVING SUBSYSTEM THEREOF AND SIGNAL PROCESSING METHOD USED THEREIN

摘要

The present invention provides a new solution to maintain the donor cell's receiving sensitivity when a repeater is connected with it. Thus the repeater will not affect the receiving performance of the donor cell. According to the present invention, a base station is proposed which comprises: an antenna for receiving a signal from a local cell; a pre-Low Noise Amplifier (pre-LNA) for amplifying the received signal by a predetermined gain; a coupler connected with the pre-LNA, a repeater for a remote cell and a processing unit of the base station, for coupling the signals from the pre-LNA and the repeater into the processing unit; and a processing unit for processing the signals from the coupler. According to the present invention, a corresponding receiving sub-system of the base station and a corresponding signal processing method used in the base station are also proposed. Furthermore, the present invention can also be used for general wireless system to improve the network performance.
