Abstract

1352859 Radio signalling SIEMENS AG 21 Dec 1971 [21 Jan 1971] 59260/71 Headings H4R and R18A1 In a radio transmission system comprising a plurality of radio relay links, on the occurrence of fading, the power of a transmitter in a link section is increased automatically. Reduction of signal strength at a receiver causes a control signal to be fed back via an auxiliary channel to increase the transmitted power at a preceding stage. The system is applicable to PCM transmission and to the use of a single carrier frequency with highly directional aerials. The auxiliary channel may form part of a service channel or free data capacity may be used and it may be a radio or a line channel.
