User Activity Detection and Channel Estimation of Spatially Correlated Channels via AMP in Massive MTC
Hamza Djelouat, Leatile Marata, Markus Leinonen +2
This paper addresses the problem of joint user identification and channel estimation (JUICE) for grant-free access in massive machine-type communications (mMTC). We consider the JU…
