FULL DUPLEX NETWORK ARCHITECTURE IN CABLE NETWORK ENVIRONMENTS

摘要

An example communication system comprises a media access control (MAC) scheduler in a cable network, and a full band transceiver. The MAC scheduler implements a two-dimensional transmission-reception (T-R) coordination scheme among a plurality of cable modems in the cable network. According to the T-R coordination scheme, the cable modems are categorized into interference groups, such that no cable modem of any one interference group transmits upstream in a frequency range simultaneously as another cable modem in the same interference group receives downstream in the frequency range, facilitating full duplex communication in the cable network across the frequency range. The full band transceiver implements an adaptive interference cancellation scheme, which suppresses at a receiver of the respective component, a signal transmitted by a transmitter of the respective component. The communication system further includes a full band amplifier, implementing the adaptive interference cancellation scheme and a ringing suppression scheme with echo cancellation.
