Multidimensional Constellations for Uplink SCMA Systems --- A Comparative Study
Monirosharieh Vameghestahbanati, Ian Marsland, Ramy H. Gohary +1
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 system, de…
Enabling Sphere Decoding for SCMA
Monirosharieh Vameghestahbanati, Ebrahim Bedeer, Ian Marsland +2
In this paper, we propose a reduced-complexity optimal modified sphere decoding (MSD) detection scheme for SCMA. As SCMA systems are characterized by a number of resource elements…
Polar Codes for SCMA Systems
Monirosharieh Vameghestahbanati, Ian Marsland, Ramy H. Gohary +1
In this paper, we design and compare multilevel polar coding (MLPC) and bit-interleaved polar coded modulation (BIPCM) for uplink sparse code multiple access (SCMA) systems that op…
The capacity region of a product of two unmatched Gaussian broadcast channels with three particular messages and a common message
Ramy H. Gohary, Timothy N. Davidson
This paper considers a Gaussian broadcast channel with two unmatched degraded components, three particular messages, and a common message that is intended for all three receivers.…
