MIMO (Multi-Input Multi-Output) is a multi-antenna signal processing method for transmitting and receiving data using a plurality of antennas in a mobile communication environment among several technologies that are attracting attention as a core technology of 4th generation mobile communication. It is a core technology that can broaden the range of wireless communication and increase the data transmission speed by transmitting two or more data signals on the same radio channel by using an antenna. It is a core technology for the recent mobile communication network system such as LTE (Long Term Evolution) .
Currently, various frequency bands are made available frequency bands in order to secure a sufficient frequency band in accordance with the generalization of mobile communication and the activation of wireless broadband data communication. In this regard, a wireless backhaul network technology for transmitting data between remote nodes communicating wirelessly with a central station connected to the core network using a carrier frequency of 10 GHz or more has been introduced.
