Abstract : A message coding is given which allows several different signal sources to asynchronously transmit binary messages over the same channel. Assuming that the messages are combined under bit by bit logical OR and are received by shift-register decoders which use the logical AND as decision devices, then a construction is given which yields a set of n different binary messages such that up to K messages can exist at any time instant in the channel. The message length grows linearly with n and as the square of K. (Author)
