Study of Joint Activity Detection and Channel Estimation Based on Message Passing with RBP Scheduling for MTC
R. B. Di Renna, R. C. de Lamare
In this work, based on the hybrid generalized approximate message passing (HyGAMP) algorithm, we propose the message-scheduling GAMP (MSGAMP) algorithm in order to address the prob…

Dynamic Message Scheduling With Activity-Aware Residual Belief Propagation for Asynchronous mMTC Systems
R. B. Di Renna, R. C. de Lamare
In this letter, we propose a joint active device detection and channel estimation framework based on factor graphs for asynchronous uplink grant-free massive multiple-antenna syste…
