Abstract
In this letter, we investigate the average symbol error rate (SER) performance of M-ary phase-shift keying (MPSK) with Tikhonov-distributed phase errors, under both intensity modulation with direct detection and heterodyne detection, in dual-hop free space optical (FSO) communication systems with fixed-gain amplify-and-forward relaying. We assume the FSO channel experiences Málaga fading with pointing errors. We derive the probability distribution function (PDF) for the end-to-end signal-to-noise ratio and use this PDF to obtain novel analytical expressions for the average SER of MPSK. Numerical results and Monte Carlo simulations validate the accuracy of these newly obtained expressions.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
