【摘要】：針對寬帶電力線資源分配中的Qo S需求保證及用戶間公平性問題,提出了一種計及接入控制策略的寬帶電力線OFDM系統(tǒng)跨層資源分配算法。首先建立了多用戶跨層資源分配系統(tǒng)模型;其次通過公平因子約束實現(xiàn)整體算法的公平性,并提出一種接入控制策略,在某一個或幾個用戶信道質(zhì)量較差而需要消耗大量系統(tǒng)資源的情況下,通過拒絕這些用戶的接入來保證系統(tǒng)的整體性能;最后,在典型電力線信道的環(huán)境下,對該算法及對比算法進行了仿真,仿真結(jié)果證明所提算法相對于對比算法可以更有效地滿足Qo S及公平性需求,提升系統(tǒng)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.
