摘要： A method for transmitting data by using a power line. The method includes: setting i=1 and j=1; receiving an i-th zero crossing signal at a time point ti, and determining, based on the i-th zero crossing signal, a start time when synchronization signals of a j-th data packet are transmitted, the start time when the synchronization signals of the j-th data packet are transmitted being ti+t; transmitting the synchronization signals of the j-th data packet at the start time when the synchronization signals of the j-th data packet are transmitted; transmitting data signals of the j-th data packet in sequence; and determining whether j is equal to M; when j is not equal to M, continuing a data transmission; and when j is equal to M, ending the data transmission, M being a number of data packets into which data to be transmitted is divided.

摘要： An integrated circuit includes a demodulator to demodulate a signal simultaneously transmitted over an isolation communication channel and obtain gate information and configuration information. The demodulator includes a gate demodulation path and a configuration demodulation path. The received signal oscillates at a first frequency to represent a first state, oscillates at different frequencies to represent a seconds state, oscillates at a third frequency (or third and fourth frequencies), which are lower than the first frequency, to represent a third state, and the received signal is steady state to represent a fourth state. The gate demodulation path detects the first and second states. The configuration demodulation path includes first and second sub-demodulation paths. An envelope detector in the first sub-demodulation path detects the second state and the second sub-demodulation path detects the third state. The configuration demodulation paths uses an output of the gate demodulation path.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a transmitting device, an indication of an instantaneous gain associated with an amplitude distortion associated with frequency division multiplexed downlink communications to the UE from the transmitting device. The UE may receive the frequency division multiplexed downlink communications from the transmitting device over frequency resources allocated to the UE, wherein receiving the frequency division multiplexed downlink communications comprises applying a digital post distortion model to the frequency division multiplexed downlink communications according to the instantaneous gain.

摘要： Some embodiments relate to systems and methods for communication of electronic signals. An example method includes receiving a first signal having a predetermined modulation. The example method includes generating a transmission for a second signal by superimposing the second signal on the modulation of the first signal by adjusting at least one of two phase states or two amplitude states of the modulation using a Reconfigurable Intelligent Surface (RIS). The example method also includes transmitting the second signal using hierarchical modulation, the predetermined modulation and the superimposed second signal on the predetermined modulation, wherein the first signal is transmitted at a higher data rate than the second signal.

摘要： Messages are transmitted in closely-spaced subcarriers in 5G and 6G, configured so that each subcarrier signal is orthogonal to the adjacent subcarrier signals. However, many effects can penetrate that orthogonality—distortion, interference, frequency variations, amplitude variations, crosstalk, etc.—collectively termed energy spill-over. To combat this problem, a receiver can determine the total energy spill-over into adjacent subcarriers by measuring a residual signal in a subcarrier with no transmission, adjacent to another subcarrier with a known transmission. The receiver can measure the amplitude, phase, temporal or spectral properties, and so forth of the residual signal. The receiver can then correct the message during signal processing, by calculating a function of the residual signal and subtracting it from each digitized subcarrier signal of a message. This can largely restore the inter-subcarrier orthogonality, improving messaging reliability while avoiding message faults and costly retransmissions.

摘要： A method for authentication of chat bots includes determining that a first chat bot is authenticated, by a server, for first session communication at a first chat session with a first chat application instance. The first chat session is hosted by a first chat service. The method includes determining authentication intent to authenticate, with the server, a second chat bot for a second session communication at a second chat session with a second chat application instance. The second chat session is hosted by a second chat service, where the first chat bot and the second chat bot simulate respective chat application instances. The method also includes providing authentication credentials, via the first chat session, to authenticate the second chat bot with the server for the second session communication.
