Patent ID: 7667780

Claim:
A channel coder for synchronizing a plurality of digital RF transmitters that are supplied a common digital signal for RF modulation and subsequent transmission on a common channel throughout a prescribed region, whereby RF receivers within said region may receive transmissions on said channel from more than one transmitter, said channel coder comprising data processing, modulation, and signal processing elements appropriate for the form of modulation used from the channel coder to the transmitters and carrying out the steps of: accepting as input the data to be transmitted; producing a signal at an intermediate RF frequency such that the transmitters can recover the digital data and process it for transmission to the prescribed region, synchronized with and by the signals from the channel coder, whereby the only limit on the bit rate of the common digital signal is the limit imposed by the channel bandwidth and form of modulation of the intermediate RF frequency signal; and outputting a signal at the intermediate RF frequency, which output signal can be transported over an analog link to the transmitters to be synchronized.
