Abstract AR
في هذا البحث تم اقراح نظام لتحسين أداء نظام متعدد النواقل متعدد الوصول لقنوات الشفرة MC-DS-CDMA في القناة اللاسلكية من ناحية تقليل معدل الخطأ.
النظام الموجود يعتمد على تحويل فورير السريع FFT.
النظام المقترح يعتمد على تحويل الميجة المتعدد MWT نتائج المحاكاة أخذت من ثلاثة أنواع من قنوات الاتصال.
المحاكاة أثبتت أن النظام المقتترح قد تفوق على النظام الموجود.
كذلك تم ملاحظة أن النظام المعتمد على تحويل المويجة المتعدد قد حقق نفس نتائج النظام المعتمد على تحويل الفورير مع الشفرة من ناحية الخسارة في عرض الحزمة مع أداء أعلى.
Abstract EN
CDMA is a multiplexing technique where a number of users simultaneously and asynchronously access a channel by modulating and spread their information-bearing signals with reassigned signature sequences [1].
The enormous growth of wireless services (cellular telephones, wireless LAN’s ...) during the last decade gives rise to the need for a bandwidth efficient modulation technique that can reliably transmit high data rates.
As multicarrier (MC) techniques combine good bandwidth efficiency with an immunity to channel dispersion, these techniques have received considerable attention.
To be able to support multiple users, the Multicarrier transmission technique can be combined with CDMA scheme.
Different combinations of the multicarrier transmission technique and CDMA are investigated in the context of high-rate communication over dispersive channels.
Two techniques that make use of carriers satisfying the orthogonally condition with minimum frequency separation are multicarrier CDMA.
