Efficient Massive Machine Type Communication (mMTC) via AMP

open access: yesIEEE Wireless Communications Letters, 2023
We propose efficient and low-complexity multiuser detection (MUD) algorithms for Gaussian multiple access channel (G-MAC) for short-packet transmission in massive machine type communications. To do so, we first formulate the G-MAC MUD problem as a sparse signal recovery problem and obtain the exact and approximate joint prior distribution of the sparse
