<p>The present invention provides a method, device and system for implementing microwave multiple-input multiple-output, relating to the field of wireless communications. The device includes a transmit channel correction module including a transmission energy distributor and a transmission coupler; the transmission energy distributor decomposes, according to a first energy distribution parameter, each channel of transmitted signals among N channels of transmitted signals into channels of transmitted sub-signals, where the number of the channels of transmitted sub-signals is the same as the number of transmit antennas, the number of transmit antennas is N, and N is a natural number greater than 1; and the transmission coupler performs phase processing on each channel of transmitted sub-signals according to a first phase parameter, selects one channel of phase-processed transmitted sub-signals from each of the N channels of transmitted signals, and combines them to obtain N channels of output signals. The present invention reduces the number of channel conditions in a MIMO system, so that a channel cascade result is equivalent to an impact of multipath on a channel, and channels in a microwave MIMO system can maintain orthogonality, thereby supporting independent transmission of multiple data streams. In addition, extra hardware is not required, achieving a smaller area of an antenna array.</p> |
