Abstract :
Degradations in the performance of any communication system can be attributed to noise or to intersymbol interference (ISI). In an optical receiver, noise contributions can either be signal-independent (e.g. electrical noise) or signal-dependent (e.g. beat noise between signal and amplified spontaneous emission (ASE), if optical preamplification is employed). Since there is no signal dispersion along the transmission tunnel in case of optical free space communication, ISI is introduced solely by bandwidth limitations within the receiver, especially if receiver bandwidths of the order of 0.5 times the data rate or less are considered. Because of ISI, reliable analytical calculations of bit error probability (BEP) are problematic in general
