This paper considers the application of multiple-input multiple-output (MIMO) techniques to
nonorthogonal multiple access (NOMA) systems. A new design of precoding and detection …

At present, non-orthogonal multiple access (NOMA) techniques have attracted broad
attentions, since they could improve the throughput of cellular networks efficiently. However …

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

This paper considers a downlink nonorthogonal multiple access (NOMA) system where the
source intends to transmit independent information to the users at target data rates under …

Non-orthogonal multiple access (NOMA) is an emerging technology that can improve
system spectral efficiency. In this paper, we propose a downlink multiple-input-multiple …

Non-orthogonal multiple access (NOMA) has been shown in the literature to have a better
performance than OMA in terms of sum channel capacity; however, the capacity superiority …

This paper proposes a unified framework of non-orthogonal multiple access (NOMA)
networks. Stochastic geometry is employed to model the locations of spatially NOMA users …

In this letter, we exploit constellation rotation to enhance the performance of uplink non-
orthogonal multiple access (NOMA) with a successive interference cancellation receiver. We …

Non-orthogonal multiple access (NOMA) is one of the key technologies being evaluated for
the fifth generation (5G) wireless communications. In this paper, a novel NOMA mechanism …

Nonorthogonal multiple access (NOMA) can effectively improve the spectral efficiency by
exploiting the power difference and employing successive interference cancellation (CSI) at …
