摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for communication time slot allocation in a communication network. In one aspect, a first network device may determine that a second network device will transmit one or more packets associated with a first latency, and determine that a third network device will transmit one or more packets associated with a second latency. The first network device may determine to allocate a greater quantity of communication time slots to the second network device than to the third network device based, at least in part, on the first latency being less than the second latency. The first network device may allocate a first plurality of communication time slots of a beacon period to the second network device, and allocate a second plurality of communication time slots of the beacon period to the third network device.

摘要： A device, system, and method for communicating with a power inverter of an array of inverters includes transmitting a relay message from an inverter array controller to a relay inverter in response to failing to receive a response from at least one power inverter of the array. The relay inverter is configured to retransmit a message from the inverter array controller to a non-responsive power inverter of the array of inverters in response to receiving the relay message. The relay inverter may subsequently retransmit a reply received from the non-responsive power inverter to the inverter array controller or to another power inverter of the array of inverters.

摘要： A method is for processing a channel analog signal coming from a transmission channel. The method may include converting the channel analog signal into a channel digital signal, and detecting a state of the transmission channel based on the channel digital signal to detect whether the transmission channel is, over an interval of time, one or more of linear and time invariant and linear and cyclostationary.

摘要： The present invention relates to inspection apparatus for use in wellbores in the oil and gas industries. In particular the invention relates in general to the field of transmission of data between downhole module in a wellbore and a controlling module at the surface. The invention provides a method and apparatus for determining analog filter parameters for an analog front end comprising a plurality of filter stages receiving signals from a telemetry module, by repeating the steps of; receiving a signal of a known frequency and processing said signal by determining the magnitude of the frequency of the received signal until a plurality of signals have been received and processed; calculating an optimum set of filter parameters in dependence upon the measured frequency magnitudes and a predefined set of filter stage frequency responses.

摘要： In a method for an optimised transmission of data in a wired multi-carrier (multi-carrier modulation—MCM) transmission system from a transmitter to one or more receivers via a transmission channel, only one specified supply power is provided for the transmitter, a transmitted signal for transmitting data has a plurality of subcarriers, and the data together with redundant information is distributed to the plurality of subcarriers in such a way that the receiver can dispense with some of the subcarriers in order to determine the data. The method includes a step of determining frequency-dependent access impedances of the wired transmission channel on the transmitter, and a step of adjusting the signal amplitude of the individual subcarriers on the basis of the measured frequency-dependent access impedances sand the limited supply power.
