Abstract AR
يقترح البحث الحالي طريقة لتصميم و محاكاة بيئة الاتصالات الخلوية باعتماد تقنيات دينامكية القفز في التردد و ذلـك لتحسـين معدل نقل البيانات و تقليل التداخل.
كما تم اقتراح عتبة لقدره المستقبلة (Pr) كإحدى تقنيات دينامكية القفز في التردد.
حيث يتم قياس القدرة المستقبلة لكل تردد في النموذج المرسلة ذات الستة ترددات و يتم تغيير أي تردد في النموذج إذا كانت القدرة المستقبلة لتـردد أقل من العتبة المحددة.
لتقم أداء النظام تم مقارنة النتائج المستحصلة لحالتي القفز في التردد و GSM.
أظهرت النتائج زيادة كفاءة الطيف باستخدام تقنية دينامكية القفز في التردد, حيث كان مساوية إلى (6.5 b/s/Hz) مقارنة مع القفـز فـي التـردد.
Abstract EN
A fundamental problem in current cellular system is how to increase spectral efficiency of cellular system and handle blocking in the call between the subscribers.
The present research offers solution to the above problem.
In this work software simulator that can be used in the environment of cellular system is designed and implemented.
This designed system shows how to increase spectral efficiency and enhancement blocking probability in cellular system by using Dynamic Frequency Hopping techniques.
In this paper received power (Pr) threshold is proposed as one method of Dynamic Frequency Hopping technique.
In each frame, received power is measured on the six used frequencies and the current hopping pattern is changed if the measured received power does not achieve the required threshold on at least one of them.
The results indicate increasing the spectral efficiency by using Dynamic Frequency Hopping technique, the result of spectral efficiency versus traffic load with Dynamic Frequency Hopping is equal to (6.5 b / s / Hz), compared with Frequency Hopping (5.2 b / s / Hz) and GSM (3.5 b / s / Hz).
This leads to an improvement in performance of system and reduce the interference allowing the users to achieve higher data rate.
