Full duplex ranging systems and methods

A system and method perform fine ranging on a plurality of cable modems in a network and distribute results. A CMTS grants access to a full duplex ranging probe to the plurality of cable modems, and probe results are distributed to the plurality of cable modems. A receive modulation error ratio (RxM...

Zusammenfassung:A system and method perform fine ranging on a plurality of cable modems in a network and distribute results. A CMTS grants access to a full duplex ranging probe to the plurality of cable modems, and probe results are distributed to the plurality of cable modems. A receive modulation error ratio (RxMER) uploaded from respective of the plurality of cable modems, and the CMTS identifies an interference group (IG) and bits/symbol for the plurality of cable moderns in a given sub-band. Full duplex operation is then performed in the given sub-band with known IG and bits/symbol.
