ملخص المقالة :
در این مقاله، یک شبکه مخابراتی تغذیه‌شده بی‌سیم چندکاربره در نظر گرفته شده که در آن کاربران و ایستگاه پایه ترکیبی به چند آنتن مجهز هستند. در فاز فروسو، ایستگاه پایه ترکیبی، سیگنال انرژی را برای کاربران ارسال کرده و در فاز فراسو، کاربران با استفاده از انرژی برداشت‌شده در فاز قبل، اطلاعات خود را با استفاده از فناوری دسترسی چندگانه فضایی به ایستگاه پایه ترکیبی ارسال می‌کنند. با در نظر گرفتن مدل عملی غیر خطی برای برداشتگر انرژی و با هدف بیشینه‌کردن مجموع نرخ، روشی بهینه را برای طراحی ماتریس پیش‌کدگذار انرژی، ماتریس‌های پیش‌کدگذار اطلاعات کاربران و زمان اختصاص‌یافته به فاز فروسو و فراسو پیشنهاد می‌دهیم. به این منظور با استفاده از تغییر متغیرهای مناسب، مسئله را به صورت یک مسئله بهینه‌سازی محدب بازنویسی کرده و روشی برای حل آن ارائه می‌کنیم. نتایج شبیه‌سازی نشان می‌دهند که در شرایط عملی، با لحاظ رفتار غیر خطی برای برداشتگر در طراحی، انرژی ارسالی کاهش و مجموع نرخ افزایش می‌یابد.
