Abstract

Adaptive resource allocation is an important issue in OFDM systems. In this paper, a new bandwidth optimization method to search for all unusable sub-channels is proposed. The new method proposed in this paper can be applied conveniently to different optimization problems (RA or MA) only by changing the initial value of the water-filling level and the formula when update the water-filling level. Simulation results show that the improved algorithm proposed based on the new method also can achieve the optimal solution to that of the well-known optimal algorithm - Greedy algorithm with lower computational complexity.
