Performance bounds and cutoff rates of quantum limited OOK with optical amplification
D. Ben-Eli, Yeheskel E. Dallal, Shlomo Shitz Shamai · 2002
The bit error probability (BER) and generalized cutoff rate (GCR) of optically amplified, direct-detection on-off keying (OOK) signaling is addressed, utilizing the classical theory of Fredholm integral equations. The approach accounts for the impact of optical bandlimiting in the Poisson regime and upper bounds on the BER are found via Chernoff techniques which address the resultant intersymbol interference (ISI) incurred by the linear pulse dispersion.>
