A time division multiple access (TDMA) waveform for controlling a MIL-STD-188-183 compliant demand assignment multiple access (DAMA) satellite communication network contains a short duration and minimal data content, time-hack, that is repeatedly transmitted by a supervisory control radio, so that the time hack occurs twice within a DAMA frame, ensuring that every radio can acquire frame synchronization, irrespective of overlap in receipt of one of the time-hacks with a voice/data channel transmission by that radio. The time-hack also identifies which one among a list of different frame formats stored in the radio is to be employed.

Timeslot assignment mechanism for satellite communication network

A device and method for controlling HF single side band radio squelch operation in which a serial tone burst indicates the start and end of a transmission and identifies an on-going transmission. Additionally, receivers in a power saving sleep mode can be activated by receipt of a set of serial tone bursts that have been transmitted with sufficient duration for the receiver to be assured the opportunity to detect them. During the subsequent transmission of information, single 'keep-alive' serial tone bursts are transmitted at random time intervals. The end of a transmission is signalled by another set of serial tone bursts. The bursts are provided with the transmitted signal on its frequency and preserve signal bandwidth.
