Joint Channel Estimation, Activity Detection and Decoding using Dynamic Message-Scheduling for Machine-Type Communications
R. B. Di Renna, R. C. de Lamare
In this work, we present a joint channel estimation, activity detection and data decoding scheme for massive machine-type communications. By including the channel and the a priori…
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…
Iterative List Detection and Decoding for mMTC
R. B. Di Renna, R. C. de Lamare
The main challenge of massive machine-type communications (mMTC) is the joint activity and signal detection of devices. The mMTC scenario with many devices transmitting data interm…
Study of Adaptive Activity-Aware Constellation List-Based Detection for Massive Machine-Type Communications
R. B. di Renna, R. C. de Lamare
In this work, we propose an adaptive list-based decision feedback detector along with an -norm regularized recursive least-squares algorithm that only requires pilot symbols (…
Study of Adaptive Activity-Aware Iterative Detection Techniques for Massive Machine-Type Communications
R. B. Di Renna, R. C. de Lamare
This work studies the uplink of grant-free low data-rate massive machine-to-machine communications (mMTC) where devices are only active sporadically, which requires a joint activit…
