Multiple access system for a vector disjunctive channel

Problems of Information Transmission. 2012. Vol. 48. No. 3. P. 243-249.
Osipov D., Frolov A., Zyablov V.

This paper addresses the problem of constructing a multiple access sys- tem for a disjunctive vector channel, similar to multiuser channel without intensity information, as described in Chang S.C., Wolf J.K. On the T-User M-Frequency Noiseless Multiple-Access Channels with and without Intensity Information // IEEE Trans. Inform. Theory. 1981. V. 27. No 1. P. 41-48.. To solve this problem a signal-code construction based on the q-ary codes is proposed. It is shown that the proposed signal-code con- struction allows to obtain the asymptotic value of the total relative rate arbitrarily close to ln 2.
