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 ...

, 2023 We consider weighted ergodic averages indexed by primes, where the weight depends on the prime, and is a "trace function" coming from algebraic geometry. We obtain extensions the classical mean-ergodic and pointwise ergodic theorems, as well as some result in the topological setting, and raise some further problems.

Some applications of log-ergodic processes: ergodic trading model and call option pricing using the irrational rotation [PDF]
Mathematics and Modeling in FinanceDue to the increasing popularity of futures trading among financial markets participants, the risk management of futures trading is of particular importance. In this paper, we study a futures trading strategy consisting of a long and a short positions by

(Uniform) convergence of twisted ergodic averages [PDF]
Ergodic Theory and Dynamical Systems, 2015 Let$T$be an ergodic measure-preserving transformation on a non-atomic probability space$(X,\unicode[STIX]{x1D6F4},\unicode[STIX]{x1D707})$. We prove uniform extensions of the Wiener–Wintner theorem in two settings: for averages involving weights coming from Hardy field functions $p$,$$\begin{eqnarray}\displaystyle \bigg\{\frac{1}{N}\mathop{\sum }_{n ...

Impact of Imperfect Angle Estimation on Spatial and Directional Modulation
IEEE Access, 2020 In this paper, we investigate the impact of imperfect angle estimation (IAE) on spatial and directional modulation (SDM) systems, assuming that the signal experiences line of sight (LoS) propagation.

Alternative Awaiting and Broadcast for Two-Way Relay Fading Channels [PDF]
, 2012 We investigate a two-way relay (TWR) fading channel where two source nodes wish to exchange information with the help of a relay node. Given traditional TWR protocols, transmission rates in both directions are known to be limited by the hop with lower ...

Infinite ergodic theory for heterogeneous diffusion processes. [PDF]
Physical Review E, 2018 We show the relation between processes which are modeled by a Langevin equation with multiplicative noise and infinite ergodic theory. We concentrate on a spatially dependent diffusion coefficient that behaves as D(x)∼|x-x[over ̃]|^{2-2/α} in the ...

The d-Shadowing Property and Average Shadowing Property for Iterated Function Systems
Complexity, 2020 In this paper, we introduce the definitions of d¯-shadowing property, d¯-shadowing property, topological ergodicity, and strong ergodicity of iterated function systems IFSf0,f1.
