Single-Layer Phase Screen With Pointing Errors for Free Space Optical Communication

Single-layer phase screen is a classical, simple and accurate approach for simulating the optical field under turbulence, it generally used in free space communication (FSOC). However, conventional single-layer studies have rarely considered pointing errors from FSOC, which prevents theoretical results mobile FSOC being verified using simulated fields. This work establishes simulation method with errors. Statistics on indicated that previous long-term average irradiance fluctuation probability density function (PDF) can be modified to better fit results. In addition, received power PDF, bit-error-rate (BER), influence of non-zero mean are investigated through The proposed provides powerful understanding evaluating comprehensive influences atmospheric turbulence FSOC.
