A New Formula for the BER of Binary Modulations with Dual-Branch Selection over Generalized-K
TL;DR: A unified closed-form expression, applicable to different binary modulation schemes, for the bit error rate of dual-branch selection diversity based systems undergoing independent but not necessarily identically distributed generalized-K fading is derived in terms of the extended generalized bivariate Meijer G-function.
Journal ArticleDOI
Performance Analysis of Free-Space Optical Links Over Málaga ( $\mathcal{M} $ ) Turbulence Channels With Pointing Errors
TL;DR: In this article, a unified performance analysis of a single-link free-space optical (FSO) link that accounts for pointing errors and both types of detection techniques is presented.
Journal ArticleDOI
Impact of Pointing Errors on the Performance of Mixed RF/FSO Dual-Hop Transmission Systems
TL;DR: In this paper, the performance analysis of a dual-hop relay transmission system composed of asymmetric radio-frequency (RF)/free-space optical (FSO) links with pointing errors is presented.
Journal ArticleDOI
Performance Analysis of Mixed Nakagami- $m$ and Gamma–Gamma Dual-Hop FSO Transmission Systems
TL;DR: A unified performance analysis of a dual-hop relay system over the asymmetric links composed of both radio-frequency and unified free-space optical links under the effect of pointing errors is carried out.

Impact of Pointing Errors on the Performance of Mixed RF/FSO Dual-Hop Transmission Systems
TL;DR: This work builds on the system model presented in to derive new exact closed-form expressions for the cumulative distribution function, probability density function, moment generating function, and moments of the end-to-end signal- to-noise ratio in terms of the Meijer's G function.
