Abstract AR
یقدم هذا البحث طریقة لأمنیة الكلام و الذي یقوم بعملیات التشفیر في مجالي الوقت و التردد و یستخدم تقنیة مهمة و هي تقنیة محول التعامد الثنائي لغرض إعطاء أنظمة الاتصالات التي تعتمد على استخدام الإشارات الكلامیة أمنیة عالیة، كذلك تم دراسة قناة الاتصال الضوضائیة التي غالبا ما ترافق عملیات التشفیر.
لقد تم الأخذ بنظر الاعتبار حالات دراسية مختلفة من خلال استخدام أنواع مختلفة من محولات التعامد الثنائي .إن كفاءة النظام المقترح درست من خلال احتساب مقیاس التقویم (نسبة الإشارة إلى الضوضاء المتقطع) و قد كانت النتائج واعدة لأنظمة تشفیر الكلام التناظریة.
Abstract EN
This paper presents speech security method which enables variety of encryption operations in the combined time and frequency spaces.
The analog speech encryption operations is performed by an important Biorthogonal transformation technique in order to give the communication systems that based on using a speech signal high degree of the security.
The noisy communication channel usually accompanying the encryption processes is studied.
Different case studies were taken into consideration, through using different types of Biorthogonal transforms.
The performance of the proposed scheme is examined through the calculation of evaluation measure (the segmental signal to noise ratio).
The results are promising for analog speech encryption systems.
