    摘要： A method and corresponding system for operating in a network in which stations communicate over a shared medium are presented. The shared medium has at least one varying channel characteristic that varies approximately periodically. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations, wherein at least some beacon transmissions are synchronized to the varying channel characteristic; and transmitting from a first station to at least one receiving station during a time slot determined based on at least one of the beacon transmissions received by the first station from the coordinator station.

    摘要： A method for generating a signal is presented. The method includes selecting a first set of carrier frequencies that are integral multiples of a first frequency interval, and selecting a second set of carrier frequencies that are integral multiples of a second frequency interval. The second frequency interval is an integral multiple of the first frequency interval and the second set is a subset of the first set. The method includes, for each of one or more signal carrier frequencies in the second set, selecting a plurality of associated carrier frequencies in the first set including a peak carrier frequency having substantially the same value as the signal carrier frequency, and modulating waveform frequency components at each of the selected plurality of associated carrier frequencies according to the same data value.

    摘要： A transmission suppression apparatus includes a first modulator that converts a symbol to a waveform. The apparatus further includes a first non-linear filter, configured to at least partially compensate for non-linear distortions of a transmission signal path. The apparatus further includes a first medium coupling device for coupling signals to a communication medium. The apparatus further includes a second medium coupling device for coupling signals from the communication medium. The apparatus further includes summing circuitry with a first input connected to an output of the second medium coupling device. The apparatus further includes cancellation circuitry, connected to a second input of the summing circuit, that converts the symbol to an analog waveform that is substantially 180 degrees out of phase with the analog waveform encoding the symbol on the first input to the summing circuit.
