Fair Resource Allocation Algorithm for OFDMA System with Imperfect CSI

open access: yesDianxin kexue, 2015
Existing resource allocation algorithms can't balance system capacity and fairness well when the channel state information is imperfect. In order to solve this problem, a fair resource allocation algorithm was proposed to maximize the system ergodic ...

Capacity Analysis of UAV-to-Ground Channels With Shadowing: Power Adaptation Schemes and Effective Capacity

open access: yesIEEE Open Journal of Vehicular Technology
In this article, an unmanned aerial vehicle (UAV), acting as a transmitter, employs different power adaptation strategies in order to enhance the ergodic capacity of the wireless channel between it and a receiver on the ground.

Ergodicity and Mixing of invariant capacities and applications

open access: yes
We introduce the notion of common conditional expectation to investigate Birkhoff's ergodic theorem and subadditive ergodic theorem for invariant upper probabilities. If in addition, the upper probability is ergodic, we construct an invariant probability to characterize the limit of the ergodic mean.

The Ergodic Capacity of Interference Networks

open access: yes, 2010
We identify the role of equal strength interference links as bottlenecks on the ergodic sum capacity of a K user interference network with the fading process restricted primarily to inde- pendent and uniform phase variations while the channel magnitudes are held fixed across time. It is shown that even though there are K(K − 1) cross-links, only about K/

Asymptotic Ergodic Capacity of Multidimensional Vector-Sensor Array MIMO Channels

open access: yesIEEE Transactions on Wireless Communications, 2008
We analyze asymptotic ergodic capacity of multidimensional vector-sensor array MIMO (PMD-MIMO) channels established by the use of dual-polarized antennas in the form of 1D, 2D and/or 3D MIMO arrays. Based on the identification of the decomposition of PMD-MIMO channels into multiple independently-fading and scaled classical MIMO channels in parallel, we

Ergodic Capacity for the SIMO Nakagami- Channel

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
This paper presents closed-form expressions for the ergodic channel capacity of SIMO (single-input and multiple output) wireless systems operating in a Nakagami- fading channel.
