摘要： Provided is a multiple input multiple output (MIMO) relay apparatus for effectively relaying MIMO signals applied to a multiple access type wireless communication system, such as a long term evolution (LTE) communication system. A transmission channel matrix between service antennas and the terminal is made as 2 X 2, MIMO signals of the base station or repeater are transmitted to the service antennas by using one cable, and two or more transceivers (or referred to as a downward/upward signal amplification unit) are disposed in the relay apparatus so as to form two or more paths in one cable, and a frequency down part and a frequency up part of at least one transceiver between two or more transceivers are separated from each other and are implemented at a donor connected to the base station or repeater in a wired or wireless manner and a service antenna so that two or more different independent paths can be formed in one cable. Also, according to an embodiment of the present invention, no backward path exists in the MIMO paths so that a manufacturing cost of the relay apparatus can be reduced.
