Dynamic Resource Assignment and Cooperative Relaying in Cellular Networks: Concept and Performance Assessment
Relays are a cost efficient way to extend or distribute high data rate coverage more evenly in next generation cellular networks. This article introduces a radio resource management solution based on dynamic and flexible resource assignment and cooperative relaying as key technologies to enhance the downlink performance of relay based OFDMA cellular networks. It is illustrated how the dynamic r...
متن کاملCooperative Relaying and Resource Allocation in Future-Generation Cellular Networks
Driven by the significant consumer demand for reliable and high data rate communications, the future-generation cellular systems are expected to employ cutting-edge techniques to improve the service provisioning at substantially reduced costs. Cooperative relaying is one of the primary techniques due to its ability to improve the spectrum utilization by taking advantage of the broadcast nature ...
متن کاملCooperative Relaying in Cellular Networks
Cooperative Relaying in Cellular Networks Sachin Kadloor Master of Applied Science Graduate Department of Electrical Engineering University of Toronto 2009 We consider a system with a single base station communicating with multiple users over orthogonal channels while being assisted by multiple relays. Several recent works have suggested that, in such a scenario, selection, i.e., a single relay...

این پایان نامه بدنبال بررسی کاربرد ارزیابی مستمر در یک محیط یادگیری زبان دوم از طریق طرح چهار سوال تحقیق زیر بود: (1) درک توانایی های فراگیران زمانیکه که از طریق برآورد عملکرد مستقل آنها امکان پذیر نباشد اما در طول جلسات ارزیابی مستمر مشخص شوند; (2) امکان تقویت توانایی های فراگیران از طریق ارزیابی مستمر; (3) سودمندی ارزیابی مستمر در هدایت آموزش فردی به سمتی که به منطقه ی تقریبی رشد افراد حساس ا...
15 صفحه اولResource Allocation for QoS-Aware OFDMA Cellular Networks with Cooperative Relaying
This paper proposes a QoS-aware resource allocation scheme, called as cooperative resource allocation scheme (CoRA), for relay-based OFDMA systems with both QoS and Best-effort (BE) users. Using CoRA, cooperative transmission between the Base-station (BS) and the Relay-station (RS) is employed to fulfill the requirements of QoS users. Moreover, resource scheduling is allowed not only at the BS ...
