Optimal Time of Arrival Estimation for MIMO Backscatter Channels
Chen He, Luyang Han, Z. Jane Wang
In this paper, we propose a novel time of arrival (TOA) estimator for multiple-input-multiple-output (MIMO) backscatter channels in closed form. The proposed estimator refines the…
Robust Joint Design for Intelligent Reflecting Surfaces Assisted Cell-Free Networks
Xie Xie, Chen He, Xiaoya Li +2
Intelligent reflecting surfaces (IRSs) have emerged as a promising economical solution to implement cell-free networks. However, the performance gains achieved by IRSs critically d…
A Joint Power Splitting, Active and Passive Beamforming Optimization Framework for IRS Assisted MIMO SWIPT System
Chen He, Xie Xie, Kun Yang +1
This paper considers an intelligent reflecting surface (IRS) assisted multi-input multi-output (MIMO) power splitting (PS) based simultaneous wireless information and power transfe…
Block-Level Unitary Query: Incorporating Orthogonal-like Space-time Code with Query Diversity for MIMO Backscatter RFID
Chen He, Z. Jane Wang, Victor C. M. Leung
Because of the emerging field of Internet of Things (IoT), future backscatter RFID is required to be more reliable and data intensive. Motivated by this, orthogonal space-time bloc…
