Ergodic capacity under channel distribution uncertainty

2014 52nd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2014
The impact of channel distribution uncertainty on the performance of fading channels is studied. The compound capacity of a class of ergodic fading channels subject to channel distribution uncertainty is obtained, for arbitrary noise and nominal channel distribution.

Ergodic Capacity of Nonlinear MIMO–OFDM Relaying Channels

Wireless Personal Communications, 2014
This paper derives the ergodic capacity of nonlinear MIMO---OFDM relaying communication channels. We consider MIMO---OFDM relaying system where the transmitter, relays, and the receiver are all equipped with $$N_t$$Nt transmitting and $$N_r$$Nr receiving antennas, and the high-power amplifiers (HPAs) at the transmitter and relays exhibit general ...

Impact of Hardware Impairments on the Outage Probability and Ergodic Capacity of One-Way and Two-Way Full-Duplex Relaying Systems

IEEE Transactions on Vehicular Technology, 2020
Hardware impairments (HI) always exist in wireless devices, especially the low-cost ones. However, due to the complicated mathematical analysis, previous studies on wireless networks usually neglected the HI, particularly for full-duplex relaying (FDR ...

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 analysis of spatially modulated systems

China Communications, 2013
Spatial Modulation (SM) is a newly introduced wireless transmission scheme, and Space Shift Keying (SSK) is its simplified version. Their capacity performance has not been well examined to date. Starting from basic definitions of information theory, through theoretical analyses and numerical calculations, this paper evaluates the capacity of SM systems

Ergodic channel capacity for generalized fading channels

2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014
The ergodic channel capacity (ECC) of single-branch receivers is studied under the scenarios described by means of α-η-μ, α-к-μ, and α-λ-μ-η generalized fading channels. Novel expressions are derived, which are the most general in this scientific area.
