Abstract :
The uncoordinated M-frequency T-user multi-access channel without intensity information is discussed. We give an approximation for the channel capacity and draw a comparison with the coordinated case. We point out, that for a larger number of users, a non-uniform input distribution must be used in both cases. Finally, we describe a coding scheme, that asymptotically achieves capacity
