    摘要: A method for causing, in a power distribution network, an oscillation allowing data to be transmitted, includes connecting at least one capacitive load in series with a modulation circuit between two wires of the network. The amplitude modulation circuit includes at least one Zener diode and at least one switch. A short make pulse is applied to the switch such that it is conductive and short-circuits the Zener diode by modulating the amplitude of the network voltage. The duration of the make pulse is such that the amplitude modulation of the network voltage causes a response of the network in the form of a high-frequency oscillation of the network voltage.

    摘要: A communications receiver may include an adaptive filter unit for removing coherent interference components from a received signal. In the absence of a signal of interest, the filter may adapt dynamically to remove current interference components. When a signal of interest is detected, the filter may be controlled to stop (or at least reduce) its adaptation, to prevent removal of the signal of interest. The received signal may be down-converted to a complex baseband by conditioning circuitry. A detector may detect the signal of interest, and control the filter. Autocorrelation may be used to estimate a characteristic of the signal of interest in the complex baseband. The detector may include hysteresis to react quickly to the start of signal of interest, and more slowly to an end of the signal of interest. The signal of interest may be a frequency shift keyed (FSK) signal. A demodulator may demodulate FSK components based on the autocorrelation result. The characteristic of the signal of interest used for detection and/or demodulation may be a directional characteristic of a vector representing the complex baseband signal in complex space.
