Full-Duplex operation has been in use since the late 1940s, from use in RADAR systems, analog telephones, digital subscriber line communications, Ethernet communications, coaxial cable communications, and wireless communications. The need to re-invent full-duplex designs for each communication system arises from the specific challenges introduced by the communication medium, hardware constraints, and operating power levels. In the case of designing interference cancellation for power line communications, we face a few additional PLC-specific issues, such as, a skewed impedance condition at the line-device interface, access-impedance-dependent echo channel that varies with changes in any part of the network, and rapid short-term channel changes influenced by the operating behaviors of various network loads. We designed customized interference cancellation solutions for broadband power line communications that counter all the above challenges.
