Advances in Relay Networks: Performance and Capacity Analysis of Space-Time Analog Network Coding

EURASIP Journal on Wireless Communications and Networking, 2010
We propose modified space-time-coding-based analog network coding (ANC) for multiple-relay network, termed space-time analog network coding (STANC). We present the performance and capacity analysis of the proposed network in terms of SER and ergodic ...

Fair Resource Allocation Algorithm for OFDMA System with Imperfect CSI

Dianxin 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

IEEE 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.

Applying a Capacity-Results Framework in Lao PDR and Other Pilot Countries

, 2005
Achieving the Millennium Development Goals (MDG) and poverty reduction objectives of developing countries requires a substantially greater investment in capacity development. This translates into action at three

CHAPTER 2 ERGODIC THEORY ON COMPACT METRIC SPACES

, 2007
Introduction. We discuss equilibria, namely measures on which supremum is attained. This Chapter provides an introduction to the theory called thermodynamical formalism, which will be the main technical tool in this book.

Upper and lower bounds for the ergodic capacity of MIMO Jacobi fading channels

, 2017
International audienceIn multi-(core/mode) optical fiber communication, the transmission channel can be modeled as a complex sub-matrix of the Haar-distributed unitary matrix (complex Jacobi unitary ensemble).

Wasserstein distance-based interference characterization and analysis in NGSO constellations with non-homogeneous stochastic geometry

Digital Communications and Networks
The performance degradation of mega Non-Geostationary Orbit (NGSO) satellite systems caused by co-frequency interference exhibits significant uncertainty, primarily due to the time-varying geometric topology, diverse communication signals, and dynamic ...
