Abstract
An efficient resource allocation scheme is presented to maximise energy efficiency for multiuser orthogonal frequency division multiple systems with proportional rate constraints. For a determined subchannel assignment, an optimal energy-efficient power allocation algorithm has been derived through a bisection search method.
