On Energy Efficient Uplink Multi-User MIMO with Shared LNA Control
Zehao Yu, Cong Shen, Pengkai Zhao +1
Implementation cost and power consumption are two important considerations in modern wireless communications, particularly in large-scale multi-antenna systems where the number of…
A Scalable Framework for CSI Feedback in FDD Massive MIMO via DL Path Aligning
Xiliang Luo, Penghao Cai, Xiaoyu Zhang +2
Unlike the time-division duplexing (TDD) systems, the downlink (DL) and uplink (UL) channels are not reciprocal anymore in the case of frequency-division duplexing (FDD). However,…
Flexible Pilot Contamination Mitigation with Doppler PSD Alignment
Xiliang Luo, Xiaoyu Zhang
Pilot contamination in the uplink (UL) can severely degrade the channel estimation quality at the base station (BS) in a massive multi-input multi-output (MIMO) system. Thus, it is…
Pilot Decontamination via PDP Alignment
Xiliang Luo, Xiaoyu Zhang, Hua Qian +1
In this paper, we look into the issue of intra-cell uplink (UL) pilot orthogonalization and schemes for mitigating the inter-cell pilot contamination with a realistic massive multi…
