الملخص

كانت الاتصالات الرقمية باستخدام MIMO واحدة من أكثر مجالات البحث الواعدة في مجال الاتصالات اللاسلكية في الوقت الحاضر لأنها تقدم الكثير من الوعود للاتصالات اللاسلكية المستقبلية. يبدو أن MIMO هي التقنية الوحيدة التي تعمل على تطوير الصناعة اللاسلكية من أنظمة 3G إلى 4G. تمت دراسة نظام MIMO بتفصيل كبير ومحاكاة لحالات مختلفة وتم التركيز على أداء طاقته في ظل ظروف بيئية عديدة. يوفر نظام MIMO مكاسب كبيرة في الأداء مقارنة بأنظمة الاتصالات اللاسلكية التقليدية. يزيد تعدد الإرسال المكاني من إنتاجية النظام دون استهلاك طيف التردد والتنوع المكاني مما يجعل الارتباط أكثر قوة. تم وصف نظام MIMO وعرض نتائج المحاكاة ومناقشتها. تعد تقنيات الهوائيات المتعددة مفتاحًا لتعزيز أداء الأنظمة اللاسلكية الحديثة.
الكلمات المفتاحية: MIMO ، تعدد الإرسال المكاني ، السعة ، التنوع ، نسبة الإشارة إلى الضوضاء (SNR)
