چکیده
Orthogonal Frequency Division Multiple Access (OFDMA) is the promising technique for ever increasing demand of high data rate services. This paper proposes the Resource allocation issues for multiuser wireless transmissions, based on orthogonal frequency division multiple Access (OFDMA) and convex optimization techniques which are widely used in the design and analysis of variety of communications problems. By using convex optimization we convert the highly non convex resource allocation problem into a sequence of convex sub problems. The proposed system will be designed, to solve the subcarrier and power allocation problems for multiuser OFDMA system. The aim of proposed system is to maximize total throughput while maintaining rate proportionality among the users and minimizing the total transmit power under the condition that the QoS requirement of each user can be guaranteed.

This paper addresses resource allocation for sum throughput maximization in a sectorized two-cell downlink OFDMA systems impaired by multicell interference. It is well known that the optimization problem for this scenario is NPhard and combinational, which is here converted to a novel sum throughput maximization problem based on the intercell interference limitation. Then, two subclasses of thi...

متن کاملResource allocation in OFDMA networks based on interior point methods
This paper studies a joint optimization problem of sub-carrier assignment and power allocation in orthogonal frequency division multiple access (OFDMA) wireless networks. A major challenge in solving the optimization problem is non-convexity caused by the combinatorial nature of sub-carrier assignment problem and/or non-convex objective functions. To address the combinatorial complexity, we for...
