Abstract: Systems, devices, and methods for isolating digital signals are described. A carrier signal can be modulated using a first signal to generate a first modulated signal. The carrier signal and the first modulated signal can be transmitted through a forward path in an isolation barrier, where transmitting the carrier signal through the isolation barrier can transform the carrier signal into a delayed carrier signal. The first modulated signal can be demodulated to recover the first signal. The delayed carrier signal can be modulated using a second signal to generate a second modulated signal. The delayed carrier signal and the second modulated signal can be transmitted through a return path in the isolation barrier, where the return path and the forward path has opposite directions.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
