Abstract :
The performance of an equal gain combining architecture for an array of photon counting receivers used in an optical PPM communication system operating in low-flux conditions is analyzed in the presence of synchronization errors. Comparisons are made to an equal gain combiner with perfect synchronization as well as to the performance of a system with timing synchronization error associated with a single large aperture. These comparisons allow one to ascertain the absolute loss due to synchronization as well as the relative loss due to independent synchronization of the elements in this optical array receiver
