چکیده

امروزه بهره‌وری انرژی در شبکه‌های مخابراتی در جهت رشد کاربران اهمیت زیادی دارد از این‌رو حضور شبکه پشتیبان بی‌سیم برای طراحی شبکه ناهمگن با بهره‌وری انرژی در شبکه‌های مخابراتی امری مهم به حساب می‌آید. در این مقاله، چارچوب کلی برای تجزیه و تحلیل بهره‌وری انرژی شبکه‌های چند لایه چند ورودی، چند خروجی ناهمگن در حضور لینک‌های پشتیبان بی‌سیم در هر دو جهت فراسو و فروسو در مجموعه‌ای از سیستم‌های مخابراتی با هدف مدیریت بهینه انرژی آن‌ها فراهم شده است. شبکه‌ای با مشختصات مفروض از جمله M آنتن در هر ایستگاه مبنا و K کاربر در هر سلول طراحی شده است و تحلیل کارآیی طیفی و برای حالت فروسو و فراسو، در شرایط مختلف با استفاده از روش‌های مختلف محاسبه و مورد مطالعه قرار گرفته است که متناسب با پیچیدگی و کارآیی طیفی روش مورد نظر اتخاذ می‌شود و مشاهده می‌شود روش یک شیوه نسبتاً رایج می‌تواند باشد، زیرا اجازه محاسبات فرم بسته کارایی طیفی در موارد خاصی مانند کانال‌های فضایی غیر هم-جوار را می‌دهد. همچنین کارآیی انرژی در دو سناریو با توان‌های مختلف مطالعه شده است و مشاهده می‌شود که کارایی انرژی با استفاده از روش‌های مختلف، تابع نامشخصی از توان عملیاتی است.

چکیده [English]

Today, energy efficiency in telecommunication networks is very important for the growth of users, so the presence of a wireless backup network is important for designing a heterogeneous network with energy efficiency in telecommunication networks. In this paper, the general framework for analyzing the energy efficiency of multi-layer multi-input networks, homogenous multi-output. This structure is provided in the presence of wireless backup links in both Up Link-Down Link directions in a set of telecommunication systems with the aim of optimal energy management. The studied network is designed with the assumed specifications of antenna M in each base station and user K in each cell. Spectral efficiency analysis and their complexity for Up Link-Down Link states were calculated and studied under different conditions using different methods. It has been observed that the method can be a common method, as it allows the calculation of the spectral efficiency of the spectral package in certain cases, such as non-adjacent spatial channels. Energy efficiency has also been studied in two scenarios with different powers, and it can be seen that energy efficiency using different methods is an indefinite function of operational power.
