摘要 针对OFDMA系统的特点,提出了一种按用户数据速率与信道条件进行资源调度分配算法。该算法在满足一定的公平性原则下,根据用户的信道参数与业务需求,动态分配子载波与传输时隙。同时还给出了该算法的具体实现步骤及在M.1225信道条件下的仿真结果,其结果表明:利用该资源调度算法可提高OFDMA系统的通过率近3倍。 A method of resource scheduling in OFDMA communication system is proposed in this paper, with this scheme, according user data rates and channel parameter, transmitting slots and subcarriers of OFDM systems are allocated dynamically. In this paper, the scheduling method and algorithm are presented and simulation results are given. The throughput of the scheduling system could be improved almost three times than moral system.
