  • In this paper, a sub-carrier allocation scheme is proposed for the future mul-tiuser mobile multimedia communication systems, which, is based on Orthogonal Frequency Division Multiplexing(OFDM) using adaptive modulation. This scheme uses an algorithm based on a rapacious optimal algorithm. Simulation result shows that this allocation algo-rithm is close to the optimum at effectiveness and efficiency with much fewer computations.
