An algorithm with polynomial time complexity, of the order of (UN log <jats:sub>2<\/jats:sub>(N)) has been proposed for sub-optimal SE maximization. Results indicate that the system SE increases with the use of SC technique. Besides, the throughput gain with SC adoption increases when the number of users (U) approaches the number of subcarriers (N) available in the system. <\/jats:p>","DOI":"10.1142\/s0218126615500619","type":"journal-article","created":{"date-parts":[[2015,2,17]],"date-time":"2015-02-17T21:41:05Z","timestamp":1424209265000},"page":"1550061","source":"Crossref","is-referenced-by-count":0,"title":["Subcarrier and Power Allocation Algorithm for Spectral Efficiency Maximization in Superposition Coding OFDMA Systems"],"prefix":"10.1142","volume":"24","author":[{"given":"Mateus","family":"de Paula Marques","sequence":"first","affiliation":[{"name":"Electrical Engineering Department, State University of Londrina, Rod.
