چکیده

در این مقاله به تحلیل عملکرد سیستم‌های رله دو راهه تداخل محدود با روش ترکیب انتخابی در گیرنده و رله تقویت و ارسال روی کانال‌های محوشدگی ناکاگامی مستقل و ناهمسان پرداخته می شود. کران‌های پایین محکمی برای احتمال قطع و نرخ خطای سرتاسری سیستم به فرم بسته به‌دست می‌آید، همچنین تحلیل مجانبی سیستم در سیگنال به نویزهای زیاد انجام می شود تا روابط مفیدی برای مرتبه چندگانگی و بهره کدینگ به‌دست آید. حالات خاص کاربردی (به عنوان مثال: حالات بی‌تداخل، توان نامحدود و کانال‌های محوشدگی رایلی) نیز بررسی شده‌اند. در ادامه، مسئله بهینه‌سازی حداقل‌سازی احتمال قطع برای سه سناریوی عملی فرمول‌بندی و حل تحلیلی می‌شود. این مسائل، مسائل بهینه‌سازی تخصیص توان با فرض مکان ثابت رله، بهینه‌سازی مکان رله با فرض تخصیص توان ثابت و بهینه‌سازی همزمان تخصیص توان و مکان‌یابی رله هستند. نتایج عددی صحت و دقت روابط استخراج‌شده را تائید کرده و دید فیزیکی مهمی از تاثیر پارامترهای مدل بر روی عملکرد سیستم را فراهم می‌آورند. به عنوان مثال نشان داده شده است که سناریوهای اول و سوم بهینه سازی نسبت به سناریوی دوم بهینه سازی عملکرد به مراتب بهتری دارند.

چکیده [English]

The performance of two-way interference-limited amplify-and-forward selective combining relaying systems over independent and non-identically distributed (i.n.i.d.) Nakagami-m fading channels is investigated. Tight lower bounds on the end-to-end outage probability and symbol error rate are derived in closed-form. An asymptotic analysis at high SNRs is done to derive useful expressions for the diversity order and coding gain. Some practical special cases (for example: interference free, infinite power, and Rayleigh fading channels cases) are also studied. Subsequently, an outage minimization problem for three practical scenarios is formulated and solved, analytically. They are power allocation under fixed relay location, relay position optimization under fixed power allocation and joint power allocation and relay position optimization problems. The numerical results confirm the correctness and accuracy of derivations and provide important physical insights into the impact of model parameters on the system performance. For instance, it is demonstrated that the first and third optimization scenarios offer significant performance enhancement over the second optimization scenario.
