Paper Abstract

The average bit error rate (BER) of optical communication systems is considered in the presence of random angular pointing jitter. The received power and the BER in the absence of jitter are reviewed and then the average BER is obtained in the presence of circularly symmetric, normally distributed jitter by using the probability density function of the optical signal. By minimizing the power penalty for average BER, the optimum ratio of the divergence angle of the laser beam to the random angular jitter at the desired BER is obtained. The derived approximation is used to determine the beam divergence angle easily against the random pointing jitter. As an example, the optimum link budget for both optical tracking and communication channels is designed in the presence of fluctuated optical signal due to random pointing jitter.
