Abstract AR
في هذا البحث يتم دراسة تأثير التشتت اللوني على أداء أحد مستقبلات ألياف الاتصال الضوئية ذو التقسيم متعدد الشفرات و هو مستقبل الربط السلبي.
و يتم استخدام الشفرات الضوئية المتعامدة.
و قد تم أخذ تأثير جميع مصادر الضوضاء في الاعتبار.
و قد تم استنتاج صورة تقريبية لمعدل الخطأ في النظام المستخدم في حالة استخدام ثلاثة أنواع مختلفة من الألياف الضوئية و هي SMF، DSF و DCF مع افتراض أن النبضات المرسلة لها شكل Gaussian.
و قد أوضحت النتائج أن تأثير التشتت يزيد مع زيادة طول الشفرة بينما زيادة وزن الشفرة يقلل من تأثير التشتت فقط عندما تكون قدرة الإشارة أقل من حد معين.
Abstract EN
In this paper the effect of chromatic dispersion on the performance of fiberoptic- code-division-multiple-access (FO-CDMA) passive correlator receiver has been investigated.
Optical orthogonal codes (OOCs) are utilized as signature sequences.
The effect of all major noise sources (quantum shot noise, dark current noise, and Gaussian circuit noise) has been taken into-consideration.
We have derived an approximate analytical expression for the bit error rate (BER) of the system.
BER analysis of the system is performed in the case of three different fiber types which are 1) a standard single mode fiber (SMF), 2) a dispersion shifted fiber (DSF), and 3) a fully dispersion compensated fiber (DCF) assuming a Gaussian pulse shape for the transmitted pulses.
The dispersion effect has been checked for different system parameters.
The numerical results demonstrate that for a fixed number of simultaneous users "N" ,the dispersion effect increases with increasing the code length "F" .It is found also that increasing code weight "k" leads to minimize the dispersion effect in the standard SMF as long as the power level is kept less than a pre-determined value.
