Coordinated Pilot Transmissions for Detecting the Signal Sparsity Level in Massive IoT Networks

Grant-free protocols exploiting compressed sensing multi-user detection (MUD) are appealing for solving the random access problem in massive Internet of Things (IoT) networks with sporadic device activity. Such protocols would greatly benefit from prior deterministic knowledge of the sparsity level,...
