We consider the multi-user detection (MUD) problem in uplink grant-free
non-orthogonal multiple access (NOMA), where the access point has to identify
the total number and correct identity of the active Internet of Things (IoT)
devices and decode their transmitted data. We assume that IoT devices use
complex spreading sequences and transmit information in a random-access manner
following the burst-sparsity model, where some IoT devices transmit their data
in multiple adjacent time slots with a high probability, while others transmit
only …
