Abstract(in Japanese) (See Japanese page)
Abstract(in English) It is shown that the capacity region of a discrete memoryless multiple access channel W with two senders and one receiver can be computed by maximizing a family of functions. J_W(P,Q), which depend upon the channel, of input distributions P and Q. An algorithm is proposed for maximizing, J_W(P,Q) in the same spirit as the Arimoto-Blahut algorithm for one-sender channels. The algorithm updates a pair of distributions (P_n,Q_n) iteratively in such a way that {J_W(R_n,Q_n)} is monotone increasing. It is shown that if J_W(P,Q) is concave and {(P_n,Q_n)} converges, then J_W((P_n,Q_n) converges to the maximum of J_W(P,Q).
