Spectral Approximation and Ergodic-Capacity Convergence of HMIMO Channels under Spatial-Wavenumber Domain Mismatch
Hangsong Yan, Hong Yang, Shu Sun
We establish quantitative results on finite-dimensional spectral approximation and ergodic-capacity convergence for continuous Holographic Multiple-Input Multiple-Output (HMIMO) ch…
Can Massive MIMO Support URLLC?
Hangsong Yan, Alexei Ashikhmin, Hong Yang
We investigate the feasibility of using Massive MIMO to support URLLC in both coherence interval based and 3GPP compliant pilot settings. We consider grant-free uplink transmission…
Optimally Supporting IoT with Cell-Free Massive MIMO
Hangsong Yan, Alexei Ashikhmin, Hong Yang
We study internet of things (IoT) systems supported by cell-free (CF) massive MIMO (mMIMO) with optimal linear channel estimation. For the uplink, we consider optimal linear MIMO r…
Channel Estimation for Reconfigurable Intelligent Surface-Assisted Wireless Communications Considering Doppler Effect
Shu Sun, Hangsong Yan
In wireless systems aided by reconfigurable intelligent surfaces (RISs), channel state information plays a pivotal role in achieving the performance gain of RISs. Mobility renders…
Joint MMSE Transceiver Design for Downlink Heterogeneous Network
Zhannan Li, Hangsong Yan, I-Tai Lu
In this paper, we propose a minimum mean square error (MMSE) based transceiver design scheme for a downlink multiple-input multiple-output (MIMO) two-tier heterogeneous network wit…
Millimeter Wave Small-Scale Spatial Statistics in an Urban Microcell Scenario
Shu Sun, Hangsong Yan, George R. MacCartney +1
This paper presents outdoor wideband small-scale spatial fading and autocorrelation measurements and results in the 73 GHz millimeter-wave (mmWave) band conducted in downtown Brook…
