Multiplex process for transmission of digital signals over single radio channel

摘要

The multiplex code is transmitted over a series of information frames ensuring checking of signal during transmission. The digital signals emitted by different logical channels are transmitted in the form of successive multiplex frames on a single radio channel. A multiplex code is transmitted (MUX) indicating the logical channels which are producing the bits of each information frame, and this multiplex code is transmitted as an integral part of an initial sync. frame preceding the information frames. This sync. frame is transmitted repetitively with the information frames. Included within each information frame there is a given number of bits representing just a fraction of the multiplex code. A complete transmission of the multiplex code is shared between a given number of successive frames.
