Antenna Selection for MIMO Systems with Closely Spaced Antennas
EURASIP Journal on Wireless Communications and Networking, 2009 Physical size limitations in user equipment may force multiple antennas to be spaced closely, and this generates a considerable amount of mutual coupling between antenna elements whose effect cannot be neglected.

Antenna Selection in Spatial Modulation Systems [PDF]
IEEE Communications Letters, 2013 Novel transmit antenna selection techniques are conceived for Spatial Modulation (SM) systems and their symbol error rate (SER) performance is investigated. Specifically, low-complexity Euclidean Distance optimized Antenna Selection (EDAS) and Capacity Optimized Antenna Selection (COAS) are studied.

Hardware Efficient Massive MIMO Systems with Optimal Antenna Selection [PDF]
Sensors, 2022 An increase in the number of transmit antennas (M) poses an equivalent rise in the number of Radio Frequency (RF) chains associated with each antenna element, particularly in digital beamforming.

Novel Receive Antenna Selection Scheme for Precoding-Aided Spatial Modulation with Lattice Reduction [PDF]
Sensors, 2022 In this paper, a new receive antenna subset (RAS) selection scheme is proposed for precoding-aided spatial modulation (PSM). First, a lattice reduction (LR)-based precoder is employed instead of a conventional zero-forcing (ZF) precoder.

Antenna Selection for Full-Duplex Distributed Antenna Systems [PDF]
IEEE Access, 2019 Full-duplex (FD) distributed antenna system (DAS) can take advantage of both FD and DAS to dramatically improve system capacity. The challenges of designing such a system are self-interference at the base station (BS) and multiuser interference, as well ...

Velocity-aware Antenna Selection in Predictor Antenna Systems
CoRR, 2021 Moving relay (MR), which is a candidate solution for supporting in-vehicle users, has been investigated in different studies. Due to the mobile nature of the MR, acquiring channel state information at the transmitter side (CSIT) is challenging because of the fast-changing environment around the vehicle.

Reliability-Security Analysis for Harvest-to-Jam based Multi-hop Cluster MIMO Networks Using Cooperative Jamming Methods Under Impact of Hardware Impairments [PDF]
EAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2021 In this paper, we consider harvest-to-jam based secure multi-hop cluster multi-input multi-output networks, where a multi-antenna source sends its data to a multi-antenna destination via multi-antenna intermediate cluster heads.

Analog Beamforming With Antenna Selection For Large-Scale Antenna Arrays [PDF]
ICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2021 In large-scale antenna array (LSAA) wireless communication systems employing analog beamforming architectures, the placement or selection of a subset of antennas can significantly reduce the power consumption and hardware complexity. In this work, we propose a joint design of analog beamforming with antenna selection (AS) or antenna placement (AP) for ...

Antenna Selection in Keyhole Channels [PDF]
IEEE Transactions on Communications, 2007 This letter presents two results for antenna selection under keyhole condition. First, we analyze the capacity of the antenna-selection keyhole channel. We show that in an MtimesN system a small number of selected antennas can match the capacity of a baseline full-antenna system (baseline system has no feedback). Second, we formally prove the intuitive
