摘要
Radio resource allocation (RRA) problem for orthogonal frequency division multiple access (OFDMA) system is considered in this paper. Based on the greedy approach, an efficient real-time suboptimal RRA algorithm, which is referred to as the fast bits-feeding algorithm in this paper, is proposed to solve both classes of RRA problems. It solves RRA optimization problems by satisfying the constraints one by one without any assumptions of bit-loading or transmission power distribution. Compared with other suboptimal methods, the performance of the proposed suboptimal algorithm is closer to that of the optimal one with even lower computational complexity, which makes it outperform other suboptimal methods.
