A Unified Framework for Non-Orthogonal Multiple Access
TL;DR: Monte Carlo simulations are presented to verify the analytical results: 1) when the number of subcarriers becomes lager, the NOMA users are capable of achieving more steep slope in terms of outage probability and 2) the outage behavior of CD-NOMA is superior to that of PD-NomA.
Journal ArticleDOI
Resource Allocation for Multi-Cell IRS-Aided NOMA Networks
TL;DR: A novel framework of resource allocation in multi-cell intelligent reflecting surface (IRS) aided non-orthogonal multiple access (NOMA) networks, where an IRS is deployed to enhance the wireless service is proposed.
Journal ArticleDOI
Performance Analysis of Non-Regenerative Massive-MIMO-NOMA Relay Systems for 5G
TL;DR: The non-regenerative massive multi-input-multi-output (MIMO) non-orthogonal multiple access (NOMA) relay systems are introduced in this paper and it is demonstrated that the ratio between the transmitter antenna number and the relay number is a dominate factor of the system performance.
Journal ArticleDOI
Joint Frame Synchronization and Frequency Offset Estimationin OFDM Systems
TL;DR: A new joint frame synchronization and carrier frequency offset estimation scheme in orthogonal frequency division multiplexing (OFDM) systems is proposed in this paper, where both frame synchronizationand carrier frequencyoffset estimation can be performed by using only ONE training symbol.
Journal ArticleDOI
Spatially Random Relay Selection for Full/Half-Duplex Cooperative NOMA Networks
TL;DR: Simulation results demonstrate that: 1) the FD-based RS schemes have better outage performance than HD- based RS schemes in the low signal-to-noise ratio (SNR) region; 2) as the number of relays increases, the pair of RS schemes considered are capable of achieving the lower outage probability.
