Joint User and Data Detection in Grant-Free NOMA with Attention-based BiLSTM Network
We assume that IoT devices use complex spreading sequences and transmit information in a random-access manner following the burst-sparsity model, where some IoT devices transmit their data in multiple adjacent time slots with a high probability, while others transmit only once during a frame.
NOMA Joint Channel Estimation and Signal Detection using Rotational Invariant Codes and GMM-based Clustering
This paper studies the joint channel estimation and signal detection for the uplink power-domain non-orthogonal multiple access.
Energy Efficient Pairing and Power Optimization for NOMA UAV Network under QoS Constraints
Furthermore, the performance and pairing complexity for mobile UAVs is analyzed to show that the proposed pairing technique efficiently fulfills their QoS requirements.
Clustering-based Joint Channel Estimation and Signal Detection for Grant-free NOMA
Since the accuracy of the utilized clustering algorithm depends on the number of the data points available at the receiver, the proposed technique delivers a tradeoff between the accuracy and block length.
