Abstract

An in-building mobile communication system. The mobile communication system in the building includes: a transmitting / receiving transponder, which performs both transmission and reception for the terminal through an antenna, and the transmitting / receiving transponder is installed in the center of the building; at least one transmitting transponder is only used to perform terminal transmission Transmitting, which is installed at a predetermined distance from the transmitting / receiving transponder, the transmitting transponder facing the transmitting / receiving transponder; at least one transmitter / receiver unit connected in parallel with the transponder; and the transmitter / receiver The base station to which the unit is connected.

Description

technical field [0001] The present invention relates to an apparatus and system for eliminating interference of received signals in a reverse link of a communication system in an enclosed space, such as a building. Background technique [0002] Generally, a mobile communication system installed in a closed space such as a building (hereinafter referred to as "in-building mobile communication system") requires a plurality of small transponders and antennas. [0003] For example, a Code Division Multiple Access (CDMA) in-building mobile communication system is used to communicate between mobile phones. A large number of small transponders can be installed in such an in-building mobile communication system. Each such transponder has an antenna for transmitting and receiving signals. [0004] However, in a communication system having a large number of transponders for transmitting and receiving signals, there is a problem that reception interference increases as the number of ...
