On the Performance of Multihop Heterodyne FSO Systems With Pointing Errors

IEEE Photonics Journal, 2015
This paper reports the end-to-end performance analysis of a multihop free-space optical system with amplify-and-forward (AF) channel-state-information (CSI)-assisted or fixed-gain relays using heterodyne detection over Gamma-Gamma turbulence fading with ...

Ergodic Capacity of D2D Underlay Communication using MC-CDMA [PDF]

Radioengineering, 2019
Device to device (D2D) communication that underlay conventional cellular networks can increase their spectrum utilization. However, since D2D users share the frequency band with cellular users, interference between these two network tiers can become a ...

Spatial Correlation and Ergodic Capacity of MIMO Channel in Reverberation Chamber

International Journal of Antennas and Propagation, 2012
It has previously been shown that a reverberation chamber can conveniently be used to measure ergodic multiple-input multiple-output (MIMO) capacity for over-the-air (OTA) tests.

Ergodicity and Mixing of invariant capacities and applications

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.

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.
