Sparse code multiple access (SCMA) is a class of non-orthogonal multiple access (NOMA)
that is proposed to support uplink machine-type communication services. In an SCMA …

Non-orthogonal multiple access (NOMA) is one promising technology, which provides high
system capacity, low latency, and massive connectivity, to address several challenges in the …

In this paper, we propose a two-user polar-coded physical-layer network coding (TU-PC-
PNC) scheme for the Gaussian multiple access channel (GMAC) to enhance the …

The progressions in telecommunication beyond the 5th generation have created a need to
improve research drifts. The current 5G study has an important focus on non-orthogonal …

Abstract Non-Orthogonal Multiple Access (NOMA) is an efficient multiple access scheme
which augments the capacity and overall throughput in LTE and 5G networks. Tackling the …

Channel equalization has been widely used to eliminate inter-symbol interference (ISI) and
improve transmission performance in fading channel. In this paper, we propose a novel …

In this paper, the uplink information-coupled polar-coded sparse code multiple access (PC-
SCMA) system is proposed. For this system, we first design the encoding method of …

Designing multidimensional constellations (MdCs) is an integral part of sparse code multiple
access (SCMA). Since the optimal maximum a posteriori (MAP) receiver for SCMA is too …

Low latency and high reliability have become two major concerns in the design of future
wireless networks. Non-orthogonal multiple access (NOMA) can achieve the high spectral …
