%X Power allocation is an important issue of resource scheduling in OFDMA system. In this paper, an algorithm of linear water-filling power allocation is proposed through searching for a rapid means for confirming the sub-carriers which need not allocate power. It can finish the process of power water-filling without time after time iterative calculation. The simulation results show that the throughput of the proposed algorithm approaches the algorithm of iterated water-filling power allocation.
