Orthogonal Frequency Division Multiple Access (OFDMA) systems commonly operate with a pseudo-random allocation of active sub-carriers to users. However, dynamic (multi-user) sub-carrier allocation (DSA) in an OFDMA system with a SISO channel has been investigated previously in [1,2]. In this paper, an alternative algorithm is proposed and evaluated. Simulation results identify gains of up to 10dB and show that near identical gain is achieved for all users.
