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…
Adaptive Switching Between Single/Concurrent Link Scheme in Single Hop MIMO Networks
Pengkai Zhao, Babak Daneshrad
Concurrent link communications built on multi-antenna systems have been widely adopted for spatial resource exploitation. MIMA-MAC, a classical MIMO MAC protocol utilizing concurre…
A Low-Delay Low-Complexity EKF Design for Joint Channel and CFO Estimation in Multi-User Cognitive Communications
Pengkai Zhao, Cong Shen
Parameter estimation in cognitive communications can be formulated as a multi-user estimation problem, which is solvable under maximum likelihood solution but involves high computa…
Performance of a Concurrent Link SDMA MAC under Practical PHY Operating Conditions
Pengkai Zhao
Space Division Multiple Access (SDMA) based Medium Access Control (MAC) protocols have been proposed to enable concurrent communications and improve link throughput in Multi-Input…
Throughput Enhancement Using Multiple Antennas in OFDM-based Ad Hoc Networks under Transceiver Impairments
Pengkai Zhao, Babak Daneshrad
Transceiver impairments, including phase noise, residual frequency offset, and imperfect channel estimation, significantly affect the performance of Multiple-Input Multiple-Output…
