摘要：A communication transmission system for electromagnetic waves comprising atransmitter, transmitting and receiving antenna with a radio link hop therebetween and areceiver having an associated diversity receiver. When there is no access to energy supply,network energy is supplied from batteries, solar systems and other power supplies whichhave limited power and are expensive. So as to provide energy saving operation of asystem, a digital system is created and the invention provides a fade detector in thereceiver for fast recognition of fading and which produces signals corresponding to theweighted switching thresholds that are derived for the connection of the diversityreceiver which had previously been disconnected so as to reduce power consumption andfor setting by reducing or increasing the transmission power or for the IF throughconnecting by way of a plurality of radio link hops or for the compensation orcancellation thereof.
