Abstract (in Japanese) (See Japanese page) 
(in English) Multiuser detection algorithms based on the belief propagation algorithm is presented.
Previously, multiuser detection algorithm based on the belief propagation algorithm was proposed however, the algorithm is the approximation of the belief propagation due to the computational complexity.
In this paper, belief propagation algorithm can be applied to the multiuser detection problems in the same way of the definition by converting the factor graph structure.
The proposed algorithm is optimum when the factor graph, which form is determined by signature sequences, has no cycles.
