Abstract: In this paper, detection of ASK optical signal in colored Gaussian noise is performed. The detection of signals in colored noise is discussed because the assumption that white noise is present in real systems is often invalid. Beside the colored noise, the laser phase noise influence on the system performance is considered. For these conditions, the likelihood ratio and the optimal receiver are determined and the system error probability is calculated.
Key words. Gaussian noise, optimal receiver, communication, optical network, amplitude shift keyng.
