Grant-Free Sparse Code Multiple Access for Uplink Massive Machine-Type Communications and Its Real-Time Receiver Design
Massive Machine-type Communications (mMTCs) is a major use case for the 5G standard. The grant-free (GF) sparse-coded multiple access (SCMA) transmission is particularly spectrum efficient in the sporadic uplink traffic, which is characteristic of the mMTC networks. In this paper, an uplink GF-SCMA...
