Asynchronous Flipped Grant-Free SCMA for Satellite-Based Internet of Things Communication Networks

Asynchronous Flipped Grant-Free SCMA for Satellite-Based Internet of Things Communication Networks

Sparse code multiple access (SCMA) is a promising code domain non-orthogonal multiple-access scheme which is able to support massive connectivity and grant-free transmission in future satellite-based Internet of Things (IoT) communication networks. Traditional grant-free SCMA is based on time synchr...
