Simulation of a Fiber-optical Communication System

Scheffel, Patricia Kay 01 January 1977 (has links) (PDF)
The feasibility of analyzing an optical communication system using standard electronic circuit analysis programs such as SCEPTRE and ASTAP is demonstrated in this thesis. The transmitter (laser and modulator) and receiver (detector and amplifier) are modelled using equivalent circuits for the various components. The transmission medium (optical fiber) is modelled using an impulse response function. Two fibers are investigated--a step-index fiber and a square-law (parabolic index) fiber.

Statistical Fading of a Plane Optical Wave in Atmospheric Turbulence

O'Hara, John F. 01 January 1980 (has links) (PDF)
A formula for the average fade time of the intensity of a plane optical wave traveling through atmospheric turbulence is developed. The model employed involves isotropic, homogeneous statistics using a lognormal distribution for the channel. The analysis is based on the fact that the logarithm of the irradiance is normally distributed and uses the work of S. O. Rice who developed such an expression for a zero mean, Gaussian process. The analysis employs the covariance function and the Taylor frozen turbulence hypothesis which results in an expression for the autocorrelation function.
