| description | A high efficiency algorithm of power and bit allocation for OFDMA system was propose,which including three parts: linear water-filling power allocation,bit allocation and power and bit adjustment. It could quickly achieve the power and bit allocation between users,and would not change the fairness performance between users. Simulation results showed that,the proposed algorithm need not iteration and could obviously decrease the operation complexity with a slight descent in system throughput contrast to other algorithms. It was promising to be used in a practical system for radio resource allocation. |
