Multiuser DMT: A Multiple Access Modulation Scheme. Diggavi, S N. In Globecom 1996, London, pages 1566–1570, 1996. abstract bibtex In this paper we propose a multiuser DMT scheme for use in a frequency dispersive multiple access channel. We formulate the problem as an optimization problem for maximizing the rate-sum or a weighted sum of the rates. We establish the rate-sum maximizing solution which is a multiuser waterfilling scheme over the DMT tones. We propose a multiuser bit-loading algorithm which finds the rate-maximizing solution in a finite number of steps.
