  • Error correction for powerline communication modem interface
    Patent number: 9280405
    Abstract: A powerline communication (PLC) power supply and modem interface can be implemented using a power supply processing unit coupled with a PLC modem unit. The power supply processing unit generates a composite PLC signal comprising a PLC signal and a DC power signal modulated with a zero cross signal (all determined from an AC powerline signal). High-powered components of the PLC modem unit can cause signal distortion in the zero cross signal component of the composite PLC signal making it difficult to extract zero cross information. An error correction unit can be implemented at the PLC modem unit to minimize the signal distortion and generate a zero cross signal with little or no error. The PLC modem unit also extracts the PLC signal and the DC power signal from the composite PLC signal, and processes the PLC signal using the zero cross information extracted from the corrected zero cross signal.

  • Mitigation of inter-network interference to enable channel reuse
    Patent number: 8483741
    Abstract: Disclosed are systems and methods for configuring a station coupled to a communication medium. Received signal powers at the station of signals transmitted from a plurality of other stations coupled to the communication medium are measured. A transmit power level of the station, used for determining powers of signals transmitted from the station, is determined based at least in part upon the received signal powers. A detection threshold of the station, used for determining which received signals to accept for further processing and which received signals to ignore, is determined based at least in part upon the received signal powers.
