Pilot-Based Unsourced Random Access with a Massive MIMO Receiver: Interference Cancellation and Power Control

In this work we treat the unsourced random access problem on a Rayleigh block-fading AWGN channel with multiple receive antennas. Specifically, we consider the slowly fading scenario where the coherence block-length is large compared to the number of active users and the message can be transmitted in one coherence block....
