In the fifth generation (5G) of wireless communication systems, hitherto unprecedented
requirements are expected to be satisfied. As one of the promising techniques of addressing …

Massive machine-type communications (mMTC) is one of the main three focus areas in the
5th generation (5G) of wireless communications technologies to enable connectivity of a …

Mobile communication systems are always in continuous evolution due to the demands of
the end-users using this technology. Therefore, before the possible launch of 5G, some …

This paper studies a downlink system that combines orthogonal-time-frequency-space
(OTFS) modulation and sparse code multiple access (SCMA) to support massive …

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 …

Interference has been a key roadblock against the effectively deployment of applications for
end-users in wireless networks including fifth-generation (5G) and beyond fifth-generation …

SCMA and polar coding are possible candidates for 5G systems. In this paper, we firstly
propose the joint iterative detection and decoding (JIDD) receiver for the uplink polar coded …

For sparse code multiple access (SCMA) with traditional codebooks, the initial information of
message passing algorithm (MPA) receiver is easily susceptible to noise and multipath …

Sparse code multiple access (SCMA) has exhibited superiority in spectrum efficiency, which
is particularly essential in the Internet of Things (IoT) system where a steadily increasing …

Sparse code multiple access (SCMA), as one of the most promising candidate techniques
for the fifth generation communications system, is a nonorthogonal multiple access scheme …
