Ergodicity of invariant capacities [PDF]
Stochastic Processes and their Applications, 2020 In this paper, we investigate capacity preserving transformations and their ergodicity. We show that for any measurable transformation $θ$ there always exists a $θ$-invariant capacity. We investigate some limit properties under capacity spaces and then give the concept of ergodicity for a capacity preserving transformation. Based on this definition, we

Ergodic Capacity of IRS-Assisted MIMO Systems With Correlation and Practical Phase-Shift Modeling [PDF]
IEEE Wireless Communications Letters, 2021 We focus on the maximization of the exact ergodic capacity (EC) of a point-to-point multiple-input multiple-output (MIMO) system assisted by an intelligent reflecting surface (IRS).

Ergodic Capacity Analysis of Satellite Communication Systems With SAG-FSO/SH-FSO/RF Transmission
IEEE Photonics Journal, 2022 Future non-terrestrial networks aim to achieve a throughput of Terabits/s. Therefore, free-space optical (FSO) communications have been adopted as a candidate solution due to their ability to achieve an extremely high data rate.

Coverage Probability and Ergodic Capacity of Intelligent Reflecting Surface-Enhanced Communication Systems [PDF]
IEEE Communications Letters, 2020 This letter studies the performance of a single-input single-output (SISO) system enhanced by the assistance of an intelligent reflecting surface (IRS), which is equipped with a finite number of elements under Rayleigh fading channels.

Approaching the ergodic capacity with lattice coding [PDF]
2014 IEEE Global Communications Conference, 2014 It is known that lattice coding can achieve the capacity of the additive white Gaussian noise (AWGN) channel. This paper addresses the performance of lattice codes in the ergodic fading channel. Using nested lattice codes and ambiguity decoding, we show that the rates achieved by lattice coding and decoding are within a constant gap of the capacity of ...

Ergodic capacity analysis of reconfigurable intelligent surface assisted wireless systems [PDF]
5G World Forum, 2020 This paper presents the analytic framework for evaluating the ergodic capacity (EC) of the reconfigurable intelligent surface (RIS) assisted systems. Moreover, high-signal-to-noise-ratio and high-number of reflection units (RUs) approximations for the EC

On the Ergodic Capacity of the Wideband MIMO Channel [PDF]
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009 In the ergodic capacity literature, the majority of results preserve the assumption of a flat-fading Gaussian channel. However, the actual wireless channels in current communication systems are often wideband and therefore time dispersive and frequency selective. In this direction, we study the ergodic capacity of a wideband MIMO channel. Starting from
