  • Double sync burst TDMA system
    Patent number: 4054753
    Abstract: A TDMA system in which each station times its respective data burst from a reference sync burst transmitted by a designated primary reference station over the satellite link. Another station transmits a secondary sync burst timed from the primary stations sync burst. To maintain synchronism at the satellite each station has a burst synchronizer operated by receipt of the primary reference sync burst. The secondary sync burst is also received by each of the stations and is capable of ensuring synchronization in case of failure of the primary stations's sync burst.

  • Distributed bit stuff decision transmission
    Patent number: 3946161
    Abstract: A stuff decision code word of multiple bit length is transmitted over a number of frames equal to the number of bits per stuff decision code word. Advantage is made of a unique word used for burst synchronization wherein a common code word is used for both stuff decision and burst synchronization. A hierarchy of bursts is established to identify the particular channel of information to which the stuff decision is associated.
