3 Terms and definitions

The terms and definitions defined in YD/T 3829-2021 and the following apply to this document. 3.1 Ground conductor groundconductor(G) A conductor in an electrical branch circuit that does not carry mains current under normal operation. NOTE. It provides a low impedance return path for ground fault current back to the service entrance panel to protect personnel and equipment and ensure circuit breaker tripping. In maintenance On the orifice panel, this conductor is bonded to the ground (ground) electrode. 3.2 MIMO channelMIMO channel A channel with multiple output ports (Tx ports) and multiple input ports (Rx ports). Note. A "2×2" MIMO channel has 2 Tx ports and 2 Rx ports. 3.3 MIMO transmissionMIMO transmission Transmission that converts one or more spatial streams into multiple transport streams. ......
