英文摘要	An analytical approach is proposed to evaluate the impact of timing jitter on the error performance of the L-ary pulse position modulation (L-PPM) free-space optical (FSO) link, under the gamma-gamma (Gamma Gamma) turbulence with pointing errors. The expression of the conditional symbol error rate (SER) for a certain timing jitter is developed while the Gaussian-Hermite polynomial approximation is utilized to derive the closed-form expression of the average SER by the jitter's variance. It is discovered that the timing jitter contributes to an error floor on the SER in both Monte-Carlo simulations and the theoretical results. Also, the jitter with small variance could be tolerable. What is more, the PPM system with lower order is more sensitive to the timing jitter than the higher ones. (C) 2017 Society of Photo-Optical Instrumentation Engineers (SPIE).
