Non-Orthogonal Multiple Access (NOMA) is superposition based multi-user transmission
technique in which multiple users' transmissions can be superimposed on each other …

Grant-free non-orthogonal multiple access (NOMA) is highly expected to support massive
connectivity and reduce the transmission latency for future wireless communications. In this …

This paper presents the design and bit error rate (BER) analysis of a phase-independent
non-orthogonal multiple access (NOMA) system. The proposed NOMA system can utilize …

Conventional non-orthogonal multiple access (NOMA) schemes assume perfect channel
state information (CSI) at the transmitter side, which is nearly impractical for many …

Non-orthogonal multiple access (NOMA) can share the same frequency band with multiple
mobile devices. In the conventional NOMA scheme, the possible pairs of users are limited …

Non-orthogonal multiple access (NOMA) has been recently considered as a promising
multiple access technique for fifth generation (5G) mobile networks as an enabling …

We present a non-orthogonal multiple access (NOMA) scheme based on combining
orthogonal frequency-division multiple access and multi-carrier code-division multiple …

In fifth-generation wireless communication networks, Non-Orthogonal Multiple Access
(NOMA) has attracted much attention in both academic and industrial fields because of its …

This paper proposes some low complexity algorithms for active user detection (AUD),
channel estimation (CE) and multi-user detection (MUD) in uplink non-orthogonal multiple …

Non-orthogonal multiple access (NOMA) has been regarded as one of the promising key
technologies for future 5G systems. In the uplink grant-free NOMA schemes, dynamic …
