Multiple Access Communication On A CATV Reverse Channel

Donald L Bitzer (Inventor), Don Lee (Inventor), John Stifle (Inventor)

Research output: Patent


A multiple access communications system links a plurality of geographically dispersed subscriber locations (each of which including a transmitter and receiver) with a central location (also including a transmitter and receiver). Multiple access communication is required in the direction from the subscriber transmitters to the central receiver. In order to maintain stability, a subscriber/transmitter which unsuccessfully transmits (due to a collision with a transmission from another subscriber) will retransmit. Multiple succeeding unsuccessful transmissions at any subscriber result at that subscriber in increasingly longer delays between successive transmissions.
