Abstract
This letter investigates the performance of coherent free‐space optical systems with multiple receivers especially through the generalised moment‐generating function based approach. Specifically, we first derive a closed‐form expression of the generalised moment‐generating function of the signal‐to‐noise ratio for the coherent free‐space optical systems. The derived generalised moment‐generating function formula is further utilised to effectively analyse the several performance metrics such as amount of fading and ergodic capacity. The accuracy of our theoretical analyses are corroborated via some numerical results.Keywords
