BER performance of FSO links over strong atmospheric turbulence channels with pointing errors
Sandalidis, H. G.; Tsiftsis, T. A.; Karagiannidis, G. K.; Uysal, M. (2008)In this letter, we investigate the error rate performance of free-space optical (FSO) links over strong turbulence fading channels together with misalignment (pointing error) effects. First, we present a novel closed-form ... -
FSO links with spatial diversity over strong atmospheric turbulence channels
Tsiftsis, T. A.; Sandalidis, H. G.; Karagiannidis, G. K.; Uysal, M. (2008)Free-space optical (FSO) communication has received much attention in recent years as a cost-effective, license-free and wide-bandwidth access technique for high data rates applications. The performance of FSO communication, ... -
Optical Wireless Communications With Heterodyne Detection Over Turbulence Channels With Pointing Errors
Sandalidis, H. G.; Tsiftsis, T. A.; Karagiannidis, G. K. (2009)We study the error performance of an heterodyne differential phase-shift keying (DPSK) optical wireless (OW) communication system operating under various intensity fluctuations conditions. Specifically, it is assumed that ... -
Optical Wireless Links with Spatial Diversity over Strong Atmospheric Turbulence Channels
Tsiftsis, T. A.; Sandalidis, H. G.; Karagiannidis, G. K.; Uysal, M. (2009)Optical wireless, also known as free-space optics, has received much attention in recent years as a cost-effective, license-free and wide-bandwidth access technique for high data rates applications. The performance of ... -
Outage probability and ergodic capacity of free-space optical links over strong turbulence
Sandalidis, H. G.; Tsiftsis, T. A. (2008)The performance of a free-space optical (FSO) communication system under strong turbulence regime that follows the K distribution is evaluated. Some useful channel statistics are derived in closed form and the outage ... -
Performance analysis of free-space optical communication systems over atmospheric turbulence channels
Nistazakis, H. E.; Tsiftsis, T. A.; Tombras, G. S. (2009)Turbulence fading is one of the main impairments affecting the operation of free-space optical (FSO) communication systems. The authors study the performance of FSO communication systems, also known as wireless optical ...
