In this work we analytically investigate optimal combiners for pre-amplified diversity receivers that operate under medium-tostrongatmosphericturbulence. We first demonstrate that the combi ner performance is strongly affected by the existence of a signal-amplified spontaneous emission beat noise at the output of the photodetector. Due to the Signac dependent nature of noise, the optimal combi ner can be classified as a hybridone,of which performance is between the well-known equalgain and maximal-ratio combiner architectures. Having established the optimal design, we further assess the proposed combiner performance over gamma-gamma and negative-exponential fading environments.
