Unsourced Random Access in MIMO Quasi-Static Rayleigh Fading Channels with Finite Blocklength
Junyuan Gao, Yongpeng Wu, Giuseppe Caire +2
This paper explores the fundamental limits of unsourced random access (URA) with a random and unknown number of active users in MIMO quasi-static Rayleigh fading chann…
