摘要： Systems and apparatuses for wireless power transfer system are described. A receiver may send an amplitude shift key (ASK) signal to a transmitter. The transmitter may receive the ASK signal from the receiver. The transmitter may perform a demodulation on the ASK signal. The transmitter may, in response to a failure to demodulate the ASK signal, encode a notification of failure in a frequency shift key (FSK) signal. The transmitter may transmit the FSK signal to the receiver. The receiver may receive the FSK signal. The receiver may perform a function to resolve the failure to demodulate the ASK signal.

摘要： A device for transmitting data includes a transmitter for generating a frequency-modulated output signal. The transmitter includes a phase-locked loop for adjusting an output frequency of the output signal to a carrier frequency, and a coupling circuit for coupling a data stream into the phase-locked loop. The output signal modulated in frequency by the coupled-in data stream has an output frequency variable over time, and the coupling circuit includes a compensation unit, which couples a compensation signal into the phase-locked loop. The compensation signal compensates at least approximately for an adjustment of the output frequency to the carrier frequency carried out by the phase-locked loop.

摘要： Automatic Gain Control (AGC) system for multi-channel signals attenuates an incoming multi-channel signal by providing a gain. The system further adjusts each individual channel, of the multi-channel signal, by supplying a second gain if needed. The AGC system is designed to ensure a received signal power is at an optimal level for analog to digital conversion or any other form of signal processing. The system also enables elimination of mid-packet gain adjustments.

摘要： A method of performing carrier frequency offset (CFO) estimation and/or time offset (TO) estimation at a radio equipment in a mobile communications system. The method allows, for each of a plurality of synchronization signal (SS) blocks (SSBs) in a SS Burst detected at said radio equipment, determining a CFO estimation and/or a TO estimation based on network information signal prediction. The method includes selecting at least some of said detected SSBs in said SSB Burst and combining the CFO estimations and/or the TO estimations to obtain improved CFO compensation and/or TO compensation for signal processing at said radio equipment.

摘要： A radio transmission apparatus determines information indicative of an estimated communications channel condition and generates a single modulation signal or a plurality of modulation signals based on the estimated communications channel condition information. The single modulation signal is transmitted from a first antenna of a plurality of antenna or the plurality of modulation signals are transmitted from the first antenna and at least a second antenna of the plurality of antenna. The plurality of modulation signals include different information from each other and are transmitted over an identical frequency band and at an identical temporal point. The single modulation signal and the plurality of modulation signals contain parameter information indicating a number of modulation signals transmitted at the same time.
