An interleaved iterative-structured joint detection algorithm for active users and frequency offsets in grant-free massive access

Great-free user access is an efficient access method for massive machine-type communications (mMTC). In the massive grant-free access, frequency offsets between users and base stations lead to the degradation of active user detection and channel estimation performance. Although traditional methods a...
