    摘要： Power line communication (“PLC”) signals are transmitted between a head-end PLC transceiver coupled to multiple remote PLC transceivers over a electric power and communications distribution network in accordance with a timing controlled PLC data frame which determines how much bandwidth is allocated to downstream transmission from the head-end to the remotes and to upstream transmissions from one or more of the remotes to the head-end. The configuration of the timing controlled data frame can be dynamically modified to achieve higher bandwidth for the downstream traffic and to satisfy changing bandwidth needs of each remote.

    摘要： The invention presents a novel method to channel estimation in OFDM systems. The embodiment of this invention is a block of new logic and modifications performed to other components of the system, added to any existing OFDM receiver, which utilizes information available from other blocks as found in the receiver. This logic would improve the units' error rate because of the improved channel quality estimations it makes available. This improvement is made possible because both channel noise data and channel signal data are used in the estimation process. This data goes through a learning process over time and multiple data blocks for further improvements in the quality of the estimate. This improvement is possible without any direct communications with other remote units, but it could be used in a multi-node environment to improve the performance of the system as the whole.

    摘要： System, apparatus and method for connecting a passive optical network (“PON”) to a power line communications (“PLC”) network using a PLC HeadEnd installed at the PON to provide for distribution of high speed, broadband data communications services available on the PON to the PLC network using high speed, broadband PLC data signals. Where the PLC HeadEnd is installed on a medium voltage power distribution network, a PLC bypass unit is installed at a medium voltage/low voltage power transformer in the PLC network to provide PLC signal connectivity between the MV and LV networks. A PLC residential gateway is installed at each end user facility, such as a home or business, desiring broadband service available on the PON.

    摘要： Data throughput rate in a power line communications (“PLC”) system is controlled by generating PLC carrier signals in accordance with a PLC signal frame structure containing payload symbols where the payload symbol length is selected based on at least one of a PLC system channel quality and node configuration data. The selected payload symbol length determines the processing operations that a source PLC transceiver performs for generating PLC signals or that a destination PLC transceiver performs for extracting information content from received PLC signals. The payload symbol lengths can be selected to maximize the data throughput rate while maintaining compatibility with prior art PLC system protocols and standards that require a PLC signal frame structure and its payload portion to have fixed, predetermined lengths.

    摘要： The trend toward moving to digital content is progressing and expanding every day. With that trend comes the availability of a multitude of content from many content sources. There is a need for this content to be distributed to multiple destinations, and there is a further need to have the content synchronized among those multiple destinations. Embodiments described herein detail a method of synchronizing this content in an asynchronous environment, such as a powerline network, including using a PHY timing flag that is used to compensate for PHY-to-channel-to-PHY delays.
