| description | The invention discloses a grouping aggregation method, device and equipment for power line communication subcarriers and a medium, and the method comprises the steps: obtaining topological noise information of a plurality of subcarriers in a power line communication network, the topological noise information comprising a topological change rate, a noise change rate, noise power and a noise type; according to the topological noise information, calculating a change time sequence of a signal to topological plus noise ratio (STNR) of each subcarrier; comparing the STNR change time sequence with a preset STNR threshold value to determine available subcarriers in the plurality of subcarriers; and grouping and distributing the available subcarriers based on the value gains of the available subcarriers in the plurality of node groups. According to the method, the color noise and the topology change rule of the communication network in a high-proportion power electronic access scene are considered, and the value gain |
