MIMO technology (Multiple-Input Multiple-Output, MIMO) refers to the use of multiple transmit and receive antennas at the transmitter and receiver, respectively, so that a plurality of antenna signals transmitted and received through the transmitting and receiving ends, thereby improving communication quality. It can make full use of space resources, through a plurality of multiple-input multiple antennas, without increasing the spectrum resources and antenna transmission power, can increase exponentially channel capacity, show a clear advantage is seen as next-generation mobile the core technology of communication.
