  • Broadcast synchronized communication system
    Patent number: 5442652
    Abstract: A communication system in accordance with the invention employs a broadcast signal for synchronization of the transmitters and receivers in the system without use of a special base transmitter for synchronizing signal transmissions. Each transmitter having a pre-assigned time slot counts from a synchronizing index which is inherent in or added to the broadcast signal to determine when to transmit. The receiver of receivers similarly count from the synchronizing index to determine when to look for specific time slice transmissions.
    Type: Grant
