Abstract :
The results obtained by Cohen, Heller, and Viterbi (1971) for an orthogonal coding technique for a particular asynchronous multiple access channel are generalized to nonorthogonal coding to investigate the gains that may be realized. It is shown that in the range of bit error probabilities of interest, for a given channel bandwidth, modest gains can be realized using nonorthogonal signaling.
