Block-Sparsity-Based Multiuser Detection for Uplink Grant-Free NOMA


Block-Sparsity-Based Multiuser Detection for Uplink Grant-Free NOMA is a scholarly work, published in 2018 in ''IEEE Transactions on Wireless Communications''. The main subjects of the publication include independent component analysis, block, computer science, technological overhead, test oracle, algorithm, computational complexity theory, compressed sensing, subspace topology, Multiuser detection, -, and frame. The paper augments activity and data detection for frame-based multi-user uplink scenarios where users are (in)-active for the duration of a frame, namely, the frame-wise joint sparsity model.
