Pattern Division Random Access (PDRA) for M2M Communications with Massive MIMO Systems
Xiaoming Dai, Tiantian Yan, Qianqian Li +2
In this work, we introduce the pattern-domain pilot design paradigm based on a "superposition of orthogonal-building-blocks" with significantly larger contention space to enhance t…

Decentralized Baseband Processing with Gaussian Message Passing Detection for Uplink Massive MU-MIMO Systems
Zhenyu Zhang, Yuanyuan Dong, Keping Long +2
Decentralized baseband processing (DBP) architecture, which partitions the base station antennas into multiple antenna clusters, has been recently proposed to alleviate the excessi…
