الملخص

     يعد الوصول المتعدد غير  المتعامد التعاوني (CNOMA) نهجا واعدا لشبكة الاتصالات في الجيل الخامس 5G . سيستفيد المستخدم من النطاق الترددي بشكل كامل دون التقيد بقيود زمنية . يوضح هذا البحث اداء المستخدم والقناة في CNOMAباستخدام  نهج التضخيم واعادة الارسال (Amplify and forward)  و نهج فك التشفير واعادة الارسال (Decode and forward ) .ويتم اجراء التحليل من خلال تغيير تقنيات تخصيص القدرة لاشتقاق افضل تكوينات النظام . النتائج التي حصلت عليها من هذا البحث هي : معدل خطأ البيانات (BER )للمستخدمين البعيدين يمكن ان يكون متطابقا مع ذلك في المستخدم القريب اذا كان هناك تخصيص قدرة بشكل صحيح وملائم وتم دراسة سعة القناة واحتمالية الانقطاع بشكل صحيح  ووجد: هناك اختلاف طفيف في سعة القناة في جميع التقنيات لعدد من المستخدمين و هناك احتمالية انقطاع للمستخدمين البعيدين رائدة عن قرب المستخدمين والقناة.
