Method of operation for a radio receiver operated close to an interfering apparatus

摘要

The method involves using a receiver (25) with a clock (29) to determine the period of blocking and unblocking sequences of an oscillator-detector (27) to make it sensitive to the signal at a nominal reception frequency. Radio waves are transmitted by nearby equipment (28) at this frequency which is subject to spaced out time periods of operation or of maximum radiation so the sensitive phase and operating or radiating phase do not coincide. The transmitted radiation may be detected and the relative phase shifted by a preset amount. A characteristic of the received signal and the equipment signal may be compared and a given shift value provided where the characteristics are different.
