Fast Tuning of Pinching Antenna-Assisted ISAC Systems via User Clustering
Ruizhi Niu, Ali Bereyhi
Pinching-antenna systems (PASSs) offer a great degree of flexibility for integrated sensing and communications (ISAC) by adapting the pinching locations for both communication chan…
Global Unknown Estimation: A Statistical Framework for Wireless Distributed Learning
Yicheng Qu, Ali Bereyhi, Ben Liang
Over-the-air computation (AirComp) is widely used for model aggregation in wireless distributed learning. Although it enhances communication efficiency, we believe the AirComp aggr…
Dynamic and Static Energy Efficient Design of Pinching Antenna Systems
Saba Asaad, Chongjun Ouyang, Ali Bereyhi +1
We study the energy efficiency of pinching-antenna systems (PASSs) by developing a consistent formulation for power distribution in these systems. The per-antenna power distributio…
Joint Receive Antenna Selection and Beamforming in RIS-Aided MIMO Systems
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +2
This work studies a low-complexity design for reconfigurable intelligent surface (RIS)-aided multiuser multiple-input multiple-output systems. The base station (BS) applies receive…
Statistical-CSI-Based Antenna Selection and Precoding in Uplink MIMO
Chongjun Ouyang, Ali Bereyhi, Saba Asaad +2
Classical antenna selection schemes require instantaneous channel state information (CSI). This leads to high signaling overhead in the system. This work proposes a novel joint rec…
Approximate Message Passing for Indoor THz Channel Estimation
Viktoria Schram, Ali Bereyhi, Jan-Nico Zaech +2
Compressed sensing (CS) deals with the problem of reconstructing a sparse vector from an under-determined set of observations. Approximate message passing (AMP) is a technique used…
RLS Precoding for Massive MIMO Systems with Nonlinear Front-End
Ali Bereyhi, Saba Asaad, Ralf R. Müller +1
To keep massive MIMO systems cost-efficient, power amplifiers with rather small output dynamic ranges are employed. They may distort the transmit signal and degrade the performance…
