Power-Minimizing Resource Allocation in Multiuser Cooperative Relay Communications
In this paper, we investigate the power-minimizing resource allocation problem in multiuser cooperative relay communication systems. A joint optimization problem involving subcarrier assignment, relay selection and power allocation is formulated. Since the problem cannot be solved directly, we decompose it into three subproblems. According to the equivalent channel gains and the target rates of...
متن کاملPower Allocation In Cooperative Relay Channels
This paper concerns power allocation in relay-assisted wireless channels for two-hop transmission. First, the transmitter sends the information to both the relay and receiver parts. Next, in the second hop, the transmitter cooperates with the relay to increase the received signal to noise ratio (SNR), assuming the relay makes use of the Amplify and Forward (AF) strategy. Moreover, it is assumed...
متن کاملResource Allocation in Cooperative Communications
In this project, we have developed a framework for resource allocation in a multi user cooperative wireless network. We have considered centralized and decentralized node-relay assignment with the objective of maximizing the sum throughput. We present an efficient polynomial time centralized assignment algorithm to achieve this objective, and also investigate efficient decentralized schemes tha...
متن کاملCooperative resource management and power allocation for multiuser OFDMA networks
Mobile network operators are facing the challenge to increase network capacity and satisfy the growth in data traffic demands. In this context, Long Term Evolution (LTE) networks, LTE-Advanced networks, and future mobile networks of the Fifth Generation seek to maximize spectrum profitability by choosing the frequency reuse-1 model. Due to this frequency usage model, advanced radio resource man...
متن کاملMinimizing Distortion via Multiuser Resource Allocation
We investigate source–controlled resource allocation for orthogonal transmission of heterogenous sources over a multiuser system. The system resources bandwidth and power are shared among all users in such a way that the average distortion for all users is minimised. Especially in mobile communications, the allocation of resources among users with different applications is a challenging task. T...
