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.

In the proposed OFDMA system, optimal resource
allocation is performed indepentendally for each user to
maximize the system performance in terms of throughput
and introduced the convex optimization tool for solving
computational complexity.
