Abstract:
1. 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 synchronised such that the second periods are synchronised with the third periods, at the radio signal receiver arrangement, such that the pulsed signal processed by the receiver arrangement is reconstituted in the bandpass filter into a continuous signal, free or substantially free of interference from the first signal, the pulsed signal processed by the receiver arrangement having a pulse rate that is greater than a bandwidth of the bandpass filter.
