Temporally-correlated massive access: joint user activity detection and channel estimation via vector approximate message passing

Abstract In the paper, we investigate a massive machine-type communication (mMTC), where numerous single-antenna users communicate with a single-antenna base station while being active. However, the status of user can undergoes multiple transitions between active and inactive states across whole con...
