AI Technical Summary
Traditional MU-MIMO systems suffer from high device matching complexity, high latency, and inability to increase uplink throughput, making effective matching difficult, especially when the number of devices is small.
By classifying the devices in a multi-user multiple-input multiple-output system, the device types are determined as airborne LOS channels, airborne NLOS channels, terrestrial LOS channels, and terrestrial NLOS channels. A specific number of terrestrial NLOS channel type and non-terrestrial NLOS channel type devices are selected for matching, and the matching process is optimized by utilizing the cross-correlation characteristics of the devices.
It enables rapid device matching, reduces matching complexity and latency, increases uplink throughput in multi-user, multi-input, multi-output systems, and ensures that the receiving end can fully decode data from multiple users.
