Abstract:
Reduce echo level may be provided by scrambling phases of echoes from multiple ports in a Full Duplex (FDX) node. The FDX node may comprise a transmit portion, a receive portion, and a plurality of ports. The transmit portion may comprise a transmit portion transmit port and a plurality of splitters. The receive portion may comprise a receive portion receive port and a plurality of combiners. The plurality of splitters and the plurality of combiners may scramble phases of completed loops from the transmit portion transmit port to the receive portion receive port resulting from reflections from the plurality of ports.
