<p>Disclosed are a system, device, and method for transmitting multi-input-multi-output signals. The system comprises a feeder distribution system, an active access host, and multiple active access slaves. The system is used for transmitting N routes of uplink/downlink signals. When transmitting the downlink signals, the active access host frequent-converts N-1 routes of downlink signals into signals having different frequencies, then transmits same to the active access slaves via the indoor-distribution system, while the active access slaves revert-frequency-convert then transmit the downlink signals. When transmitting the uplink signals, the active access host frequent-converts the uplink signals then transmits same to the active access slaves via the indoor-distribution system, and the active host revert-frequency-convert the uplink signals then transmits same to a base station or an RRU. N is an integer greater than or equal to 2. The technical solution of the present invention allows for the utilization of a standalone feeder distribution signal for multi-input-multi-output transmission, thus reducing installation costs.</p> |
