Joint Estimation of Clustered user Activity and Correlated Channels with Unknown Covariance in mMTC
ICASSP 2023accepted
This paper considers joint user identification and channel estimation (JUICE) in grant-free access with a clustered user activity pattern. In particular, we address the JUICE in massive machine-type communications (mMTC) network under correlated Rayleigh fading channels with unknown channel covarian…
