Telegram transmission on one single carrier frequency - involves telegrams with fixed length and fixed spacings, and spacings are different in different transmitters

摘要

The telegram has an address, and is sent by transmitters with equal priorities to a receiver with an address in a remote control system. Individual pulse telegrams from each sender have a fixed duration and a fixed spacing between them. The ratio between telegram duration and spacing is different in each station, with the shortest spacing between telegrams much longer than the length of the longest telegram. Pulse telegrams at the senders are always sent in the specified pulse grid.
