Abstract AR
في هذه الورقة تـمت دراسة استخلاص البيانات من إشارة الطيف المنتشر ذي التعاقب المباشر في الاتصالات عبر قنوات ذات خصائص غير معروفة.
و لقد تم اقتراح خوارزمية جديدة مبنية على تقدير لأقصى تعاقب محتمل يجمع بين التعرف إلى القناة ذاتها و بين استعادة البيانات المرسلة.
للخوارزمية المقترحة إلى ميزة من حيث جاهزيتها للتطبيق المتوازي, إضافة إلى كفاءتها الحسابية العالية.
و لقد تم إبراز نتائج المحاكاة التي تعكس مدى فاعلية تلك الخوارزمية المقترحة في هذا البحث.
Abstract EN
In this paper, the problem of blind data demodulation of direct sequence spread spectrum signals for communications over dispersive channels with unknown parameters is considered.
A new algorithm based on the maximum likelihood sequence estimation (MLSE) for joint channel identification and data recovery is proposed.
The proposed algorithm has an advantage in that it is amenable to parallel implementation and is computationally efficient.
Simulations results illustrating the effectiveness of proposed algorithm have been presented.
