摘要： A communications system comprising a signal transmission arrangement for outputting a first signal for transmission, a first controller operable to control transmission of the first signal such that the transmitted signal takes a pulsed form including a plurality of first periods in which the first signal is transmitted separated by second periods in which the first signal is not transmitted, a radio signal receiver arrangement including or forming a bandpass filter and arranged to receive a second signal, and a second controller operable such that during a plurality of third periods the second signal is processed by at least part of the radio receiver arrangement, the third periods being separated by fourth periods in which the radio receiver arrangement does not process the second signal, wherein the first and second controllers are synchronized such that the second periods are synchronized with the third periods, at the radio signal receiver arrangement, such that the pulsed signal received by the receiver arrangement is reconstituted in the bandpass filter into a continuous signal, free or substantially free of interference from the first signal.

摘要： A receiver and associated methods are described. The receiver comprises a first oscillator 14, a second oscillator 16, a controller 18 operable to control frequencies to which the first and second oscillators are tuned, and a discrimination circuit 24 operable to receive and monitor transmitted signals; wherein the discrimination circuit is configured to receive a signal at a first transmission frequency determined based on a first tuned frequency to which the first oscillator is tuned, and to determine, in a capture time period, whether data is being transmitted at the first transmission frequency; wherein the controller is configured to tune, in a tuning time period, the second oscillator to a second tuned frequency; and wherein the tuning time period is shorter than the capture time period.
