Many Access for Small Packets Based on Precoding and Sparsity-aware Recovery [PDF]
Modern mobile terminals produce massive small data packets. For these short-length packets, it is inefficient to follow the current multiple access schemes to allocate transmission resources due to heavy signaling overhead.
