【摘要】：针对宽带电力线资源分配中的Qo S需求保证及用户间公平性问题,提出了一种计及接入控制策略的宽带电力线OFDM系统跨层资源分配算法。首先建立了多用户跨层资源分配系统模型;其次通过公平因子约束实现整体算法的公平性,并提出一种接入控制策略,在某一个或几个用户信道质量较差而需要消耗大量系统资源的情况下,通过拒绝这些用户的接入来保证系统的整体性能;最后,在典型电力线信道的环境下,对该算法及对比算法进行了仿真,仿真结果证明所提算法相对于对比算法可以更有效地满足Qo S及公平性需求,提升系统性能。
[Abstract]:In view of the Qo S requirement guarantee and fairness among users in the resource allocation of broadband power lines, a cross layer resource allocation algorithm for broadband power line OFDM system is proposed. First, a multi user cross layer resource allocation system model is established. Secondly, the fairness of the overall algorithm is realized by the fairness constraint, and it is proposed. An access control strategy is given to ensure the overall performance of the system by rejecting the access of these users in the case of poor quality of one or several user channels and the need to consume a large number of system resources. Finally, the algorithm and the ratio algorithm are simulated under the environment of a typical power line channel. The simulation results prove that the proposed algorithm is proposed. Compared with the contrast algorithm, the method can more effectively meet the requirements of Qo S and fairness, and enhance the performance of the system.
