摘要： Aspects are directed to communicating data over power distribution lines carrying alternating current, using a communication protocol for communicating data between endpoint devices and an upstream data-collecting device. From first symbols having a plurality of bits, at least two second symbols are generated, the second symbols respectively including different subsets of the bits in the first symbol. Each first symbol is split into second symbols having a predefined bit size for an encoding operation that operates on entire symbols having the predefined bit size (e.g., smaller than the bit size of the first symbols). The second symbols are encoded and combined according to the communication protocol. The encoded symbols are communicated over the power distribution lines based on timing indicated at least in part by the alternating current.

摘要： Aspects of the present disclosure are directed toward receiver devices and methods of using receiver devices. One such method can include converting, using an analog-to-digital converter (ADC), and an analog input signal from power distribution lines that carry power using alternating current (AC) to a digital form. This input digital signal can be an oversampled digital signal, where the digital signal is oversampled relative to downstream processing (e.g., FFT-based processing). A processing circuit(s) can then be used to decimate the input digital signal according to a decimation rate. A reference signal can be generated by the processing circuit that is responsive to the decimation rate. The processing circuit can also be used to detect a change in a phase difference between the AC and reference signal and to modify, in response to detecting a change in the phase difference, the decimation rate to counteract the detected change in the phase difference.

摘要： Aspects of the present disclosure are also directed towards a method that includes maintaining a transmission period which has a start time and an end time synchronized to metrological time. Further, this method, in response to the start time, begins transmission of a frame, which includes a plurality of symbols. This transmission occurs over power distribution lines that carry power using alternating current (AC). This method also includes synchronizing a transmission time for each symbol of the plurality of symbols according to a time-based parameter of the AC. In response to reaching an end of the frame, a synchronization symbol period is determined for a synchronization symbol, as a function of the transmission times, for the plurality of symbols and time from the end of the frame to the end time. The synchronization symbol is then transmitted on the power distribution lines.

摘要： Disclosed are various embodiments of an input signal combiner. In one embodiment, a receive stage receives a multi-phase waveform and separates the multi-phase waveform into a plurality of waveforms. Analog-to-digital converters convert the plurality of analog waveforms into at least one digital signal. At least one gain stage adjusts an amplitude of each of the digital signals and combines the amplitude adjusted digital signals into at least one gain adjusted combined signal. A signal extraction stage extracts an inbound signal from the at least one gain adjusted combined signal according to a demodulation scheme.

摘要： A system for bi-directional communication within a power distribution system. The system is configured to find an endpoint, the endpoint having an endpoint transceiver in electrical communication with a power distribution line. The power distribution line is within the power distribution system, and the endpoint is identified by a unique I.D. The system comprises a substation transceiver electrically coupled to a power distribution line within the power distribution system. A substation circuit is in electrical communication with the substation transceiver. The substation circuit is programmed to map the unique I.D. for the endpoint to a base frequency within a bandwidth and to control the endpoint to transmit a find endpoint data packet onto the power distribution network. The find endpoint data packet includes the unique I.D. and the base frequency. The substation circuit is further programmed to assign a status to the base frequency upon receiving a signal from the endpoint, the status indicating that the substation transceiver is receiving signals in the frequency bandwidth.
