Performance Analysis of Reconfigurable Holographic Surfaces in the Near-Field Scenario of Cell-Free Networks Under Hardware Impairments
Qingchao Li, Mohammed El-Hajjar, Yanshi Sun +1
We propose a hybrid beamforming architecture for near-field reconfigurable holographic surfaces (RHS) harnessed in cell-free networks. Specifically, the holographic beamformer of e…
Energy-Efficient Reconfigurable Holographic Surfaces Operating in the Presence of Realistic Hardware Impairments
Qingchao Li, Mohammed El-Hajjar, Yanshi Sun +3
Reconfigurable holographic surfaces (RHSs) constitute a promising technique of supporting energy-efficient communications. In this paper, we formulate the energy efficiency maximiz…
Achievable Rate Analysis of Intelligent Omni-Surface Assisted NOMA Holographic MIMO Systems
Qingchao Li, Mohammed El-Hajjar, Yanshi Sun +4
An intelligent omni-surface (IOS) assisted holographic multiple-input and multiple-output architecture is conceived for full-space coverage at a low energy consumption.…
Geometrically-Shaped Multi-Dimensional Modulation Formats in Coherent Optical Transmission Systems
Bin Chen, Yi Lei, Gabriele Liga +4
Shaping modulation formats in multi-dimensional (MD) space is an effective approach to harvest spectral efficiency gains in both the additive white Gaussian noise (AWGN) channel an…
A Soft-Aided Staircase Decoder Using Three-Level Channel Reliabilities
Yi Lei, Bin Chen, Gabriele Liga +3
The soft-aided bit-marking (SABM) algorithm is based on the idea of marking bits as highly reliable bits (HRBs), highly unreliable bits (HUBs), and uncertain bits to improve the pe…
Nonlinear Interference Analysis of Probabilistic Shaping vs. 4D Geometrically Shaped Formats
Bin Chen, Chigo Okonkwo, Alex Alvarado
Performance trade-offs between linear shaping and nonlinear tolerance of the recently introduced 4D orthant-symmetric 128-ary modulation format are investigated. Numerical simulati…
