Ergodic Capacity and Placement Optimization for RSMA-Enabled UAV-Assisted Communication

IEEE Systems Journal, 2023
This work investigates the performance of a downlink wireless network consisting of an unmanned aerial vehicle (UAV)-assisted base station (BS) that uses rate-splitting multiple access (RSMA) to serve multiple ground users (GUs) simultaneously.

Outage Probability and Ergodic Capacity of Distributed Transmit Beamforming With Imperfect CSI

IEEE Transactions on Vehicular Technology, 2022
In this paper, we present unified performance analysis framework of distributed transmit beamforming (DTB) with residual phase errors which arise from various sources such as imperfect synchronization and channel feedback quantization. More specifically,

Outage Probability and Ergodic Capacity of User Clustering and Beamforming MIMO-NOMA Relay System With Imperfect CSI Over Nakagami-$m$ Fading Channels

IEEE Systems Journal, 2021
Although the theory of nonorthogonal multiple access (NOMA) has been widely investigated, so far, there is a lack of applying beamforming into NOMA systems.

Ergodic Capacity Analysis of OFDM-based NB-PLC Systems

International Conference on Advanced Communication Technology, 2022
Power line communication (PLC) has been proposed as a crucial part of smart grid applications. This is due to its capacity to use existing power-grid infrastructure to provide cost-efficient data transmissions.

Ergodic Capacity of a DSL Binder Channel

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
The goal of this paper is to investigate the capacity of a symmetric Digital Subscriber Line (DSL) channel under Gaussian interference and thermal noise. Previous efforts only considered various analytical worst-case channel models to calculate the capacity of the DSL channel.

Ergodic capacity ordering of fading channels

2012 IEEE International Symposium on Information Theory Proceedings, 2012
In this paper, a new stochastic order between two fading distributions is introduced. A fading channel dominates another in the capacity ordering sense, if the ergodic capacity of the first is greater than that of the second at all values of average signal to noise ratio.

On the Ergodic Secrecy Capacity of Intelligent Reflecting Surface Aided Wireless Powered Communication Systems

IEEE Wireless Communications Letters, 2022
This letter studies physical layer security (PLS) of an intelligent reflecting surface (IRS) aided wireless powered communication (WPC) system in the presence of a passive eavesdropper, and proposes three secure IRS-WPC modes.

Achieving the ergodic capacity with lattice codes

2015 IEEE International Symposium on Information Theory (ISIT), 2015
The performance of lattice codes in the additive white Gaussian noise (AWGN) channel has attracted much attention lately, however, their performance under ergodic fading channels has been relatively unexplored. We show that lattice coding and decoding achieve the capacity of the ergodic point-to-point and multiple-access channels (MAC). Additionally, a
