Massive MIMO-OFDM Channel Acquisition with Multi-group Adjustable Phase Shift Pilots
Yu Zhao, Li You, Jinke Tang +4
Massive multiple-input multiple-output - orthogonal frequency division multiplexing (MIMO-OFDM) systems face the challenge of high channel acquisition overhead while providing sign…
Pinching-Antenna-based Communications: Spectral Efficiency Analysis and Deployment Strategies
Mengyu Qian, Xidong Mu, Li You +1
A multiple-waveguide pinching-antenna (PA)-based multi-user communication system is investigated. With a given number of PAs, two deployment strategies are considered, namely the c…
Continuous Aperture Array (CAPA)-Based Multi-Group Multicast Communications
Mengyu Qian, Xidong Mu, Li You +1
A continuous aperture array (CAPA)-based multi-group multicast communication system is investigated. An integral-based CAPA multi-group multicast beamforming design is formulated f…
Spectral Efficiency Analysis of Near-Field Holographic MIMO over Ricean Fading Channels
Mengyu Qian, Xidong Mu, Li You +2
With the denser distribution of antenna elements, stronger mutual coupling effects would kick in among antenna elements, which would eventually affect the communication performance…
