In this work, we develop a pair of rate-diverse encoder and decoder for a two-user Gaussian
multiple access channel (GMAC). The proposed scheme enables the users to transmit with …

Rate-splitting multiple access (RSMA) is a promising multiple access (MA) technique. It
employs rate-splitting (RS) at the transmitter and successive interference cancellation (SIC) …

Constellation Constrained (CC) capacity regions of two-user Single-Input Single-Output
(SISO) Gaussian Multiple Access Channels (GMAC) are computed for several Non …

Sparse Code Multiple Access (SCMA) is a disruptive code-domain non-orthogonal multiple
access (NOMA) scheme to enable future massive machine-type communication networks …

This paper studies non-orthogonal transmission over a K-user fading multiple access
channel. We propose a new reliable physical-layer network coding and cascade …

We study code design for two-user Gaussian multiple access channels (GMACs) under fixed
channel gains and under quasi-static fading. We employ low-density parity-check (LDPC) …

In sparse code multiple access (SCMA)-based grant-free (GF) access, both user's channel
and the selected SCMA codebook (CB) are considered as a transmission signature for multi …

Rate-splitting multiple access (RSMA) has emerged as a novel, general, and powerful
framework for the design and optimization of non-orthogonal transmission, multiple access …

Interleave-Division Multiple Access (IDMA) has recently been proposed by a number of
authors. By means of Monte Carlo simulations, a performance close to the capacity limit has …

The complex Gaussian multiple-access channel (GMAC) Y_= AX_+ N_ is considered. The
transmitters send information independently with a power constraint so that X_ has a product …
