Wireless-Powered Communication Networks With Random Mobility [PDF]
IEEE Access, 2019 في هذه الورقة، ننظر في شبكة اتصالات لاسلكية تعمل بالطاقة (WPCN)، حيث يتواصل مصدر معلومات متعدد الهوائيات محدود الطاقة، مدعوم من منارة طاقة مخصصة، مع مستخدم جوال (MU). تم تجهيز MU بهوائي واحد وتتميز حركتها بنموذج التنقل العشوائي المعروف. للحصول على المزايا باستخدام هوائيات متعددة في المصدر، نعتمد نظامين شائعين لنقل الهوائي المتعدد، وهما الإرسال الأقصى ...
