| Abstract | ||
| In this paper, the equations which limit the (ADP) for receiver circuits by the effect of noise had derived. The effect of laser intensity on the direct detection of digital optical communication system is also analyzed and studied. We found that, a best performance gain is obtained depending on the maximum value of the signal to noise ratio (S/N). optimizing the (ADP) gain reduces the impact of the this noise on the system performance and power penalty bit error rate (BER) and yields a power penalty which is relatively less affected by ionization rate of the detector. The Mat lab language is used to clarify the graphics in this work . | ||
