Abstract :
The performance in estimating a Wiener process that modulates the phase of a subcarrier in a direct-detection optical communication system is studied. An approximation is derived for the steady-state probability density of the estimation error. The meansquare estimation error predicted using this density is compared to theoretical lower bounds on the error and to the sample meansquare error obtained by simulation.
