Focusing on intensity-modulation/ direct-detection (IM/DD) partially coherent optical links using the on-off-keying scheme
the analytic models of channel capacity
channel bit-error-rate and link outage probability were established.On the basis of these models
the calculations of channel capacity
channel bit-error-rate and link outage probability for both fully and partially coherent optical links were performed
and then the comparative analysis for the two types of links was presented.The optimization model for the initial coherent degree of a laser was proposed with the situation when the transmitted power was limited.The performance of optical links through atmospheric turbulence using partially coherent beams is better than fully coherent beams
and propagation using a partially coherent beam is an effective technique for mitigating the turbulence-induced impact.
