frequency-division multiplexing (OFDM) in … the nonlinearity for digital NOMA-OFDM systems with …

… Hence, a hyperparameter-free receiver, which does not require tuning of any … -free receiver
for GF-NOMA with massive MIMO-OFDM, incorporating the pilot design considered in [14] to …

… RECEIVER DESIGN This section is concerned with the receiver design for the nonlinear
NOMA-OFDM system described above. We define the channel frequency responses between …

… NOMA performance gains. In this paper, we evaluate downlink NOMA link-level performance
with multiple receiver designs and … In each resource block, we assume there are 14 OFDM …

… receiver in the presence of synchronization error or CFO. As correct estimation of the channel
and CFO is crucial for OFDM-NOMA, … pre-coding technique for OFDM-NOMA with different …
