摘要： To provide a transmission system capable of ensuring reliability of signal transmission. The transmission system includes: a remote unit alternately outputting pulse voltage with a positive polarity and pulse voltage with a negative polarity as a signal by causing a first switching element and a second switching element to alternately open and close; and a master unit accepting input of a signal from the remote unit via a cable, and separating the signal into a first signal corresponding to the pulse voltage with the positive polarity and a second signal corresponding to the pulse voltage with the negative polarity.

摘要： Various embodiments include methods performed in receiver circuitry of a wireless communication device for demodulating wireless transmission waveforms to reconstruct data tones, which may include receiving, from a transmitter, wireless transmission waveforms that includes peak reduction tones (PRTs) that were inserted by a PRT neural network in the transmitter, and demodulating the received wireless transmission waveforms using a decoder neural network that has been trained based on outputs of the transmitter to output a reconstruction of the data tones. Further embodiments include exchanging information between the transmitter and receiver circuitry to coordinate the PRT neural network used for inserting PRTs in the transmitting wireless communication device and the decoder neural network used in the receiving wireless communication device for demodulating transmission waveforms received from the transmitting wireless communication device.

摘要： A data transmission system includes a first circuit, a second circuit, and a reference voltage generation circuit. The first circuit includes a transmitter powered by a first power supply voltage and having an input for receiving a data output signal, and an output. The second circuit includes a receiver powered by a second power supply voltage and having a first input coupled to the output of the transmitter, a second input for receiving a reference voltage, and an output for providing a data input signal. The reference voltage generation circuit forms the reference voltage by mixing a first signal generated by the first circuit based on the first power supply voltage and a second signal generated by the second circuit based on the second power supply voltage.

摘要： A wire-line transceiver is configured to perform a serial loop back test. The wire-line transceiver includes an on-chip transmitter, an on-chip receiver and a fractional feed forward equalizer circuit (fractional FFE circuit) in a serial loop back line path between the on-chip transmitter and the on-chip receiver. The fractional FFE circuit is configured to induce a delay one of less than one symbol time of data, for enhancing an eye opening from the serial loop back line during the serial loop back test, compared to a situation where the fractional FFE circuit is not present or is not used.

摘要： A method for tunning high speed link parameters for cables with a transceiver at each end includes transmitting, in response to establishing a link, an eye pattern bit sequence from a first computing device to a second computing device over a cable with a transceiver connected to each end of the cable. Establishing the link includes establishing a communication link over the cable between the first computing device and the second computing device. The method includes receiving an eye pattern quality message from the second computing device using a device discovery protocol. The eye pattern quality message includes quality information of a received waveform corresponding to the transmitted eye pattern bit sequence. The method includes adjusting transmission parameters for transmission over the cable in response to the quality information, and retransmitting the eye pattern bit sequence using the adjusted transmission parameters.

摘要： The power line communication device detects inverter noise from the voltage waveforms of the power line, and executes the output of the transmission signal in a period in which it is determined that the signal amplitude of the transmission signal in the transmission processing unit exceeds a predetermined value from the output amplitude of the inverter noise, and stops the output of the transmission signal in other periods.

摘要： Disclosed are a high-voltage pulse generator and a communication method therefor. The high-voltage pulse generator comprises a master controller and a sub-controller. Data transmitted between the master controller and the sub-controller at least comprise a first class of data and a second class of data, and, the second class of data at least comprise two types. The communication method comprises the following steps: during the present instance of transmitting a first class of data, transmitting partial types of a second class of data; during the next instance of transmitting the first class of data, transmitting other types of second class of data; and repeatedly executing the step until the transmission of all types of second class of data is completed. The present application ensures an increased real time performance in the transmission of the first class of data; moreover, controller pin resources occupied are reduced, costs are reduced, and the problem of data conflict is avoided.
