LoS Blockage in Pinching-Antenna Systems: Curse or Blessing?
Zhiguo Ding, H. Vincent Poor
This letter is to investigate the impact of line-of-sight (LoS) blockage on pinching-antenna systems. Analytical results are developed for both single-user and multi-user cases to…
MIMO-PASS: Uplink and Downlink Transmission via MIMO Pinching-Antenna Systems
Ali Bereyhi, Chongjun Ouyang, Saba Asaad +2
Pinching-antenna systems (PASSs) are a recent flexible-antenna technology that is realized by attaching simple components, referred to as pinching elements, to dielectric waveguide…
Flexible-Antenna Systems: A Pinching-Antenna Perspective
Zhiguo Ding, Robert Schober, H. Vincent Poor
Flexible-antenna systems have recently received significant research interest due to their capability to reconfigure wireless channels intelligently. This paper focuses on a new ty…
Hybrid NOMA Assisted OFDMA Uplink Transmission
Zhiguo Ding, H. Vincent Poor
Hybrid non-orthogonal multiple access (NOMA) has recently received significant research interest due to its ability to efficiently use resources from different domains and also its…
Next Generation Multiple Access for IMT Towards 2030 and Beyond
Zhiguo Ding, Robert Schober, Pingzhi Fan +1
Multiple access techniques are fundamental to the design of wireless communication systems, since many crucial components of such systems depend on the choice of the multiple acces…
Design of Downlink Hybrid NOMA Transmission
Zhiguo Ding, Robert Schober, H. Vincent Poor
The aim of this paper is to develop hybrid non-orthogonal multiple access (NOMA) assisted downlink transmission. First, for the single-input single-output (SISO) scenario, i.e., ea…
