Non-orthogonal Multiple Access design via Frame Theory
Shunya Nishikawa, Hiroki iimori, Giuseppe Abreu (Rits Univ.) RCS2017-402
Abstract (in Japanese) (See Japanese page) 
(in English) We propose a non-orthogonal multiple access (NOMA) scheme based on frame theory. In the proposed design, the interference of multiple users mapping to a finite number of power levels, each consisting on the overlap of the same number of users. The result is an interference scenario similar to that imposed by sparsity of Latin matrices employed in the sparse coded multiple access (SCMA) method, with the advantage that in the proposed scheme all users are able to simultaneously take advantage of the entire spectrum.
