摘　　要：针对宽带电力线载波通信资源分配问题,提出一种物理层资源分配算法,满足低复杂度的需求。首先,基于等功率分配方法,确定每个用户满足其最小速率要求所需的子载波集合,资源分配中的多用户问题可以拆分为单用户问题,并满足最优功率分配,然后将拉格朗日乘子法用于优化每个用户使用的子载波集的功率,以进一步提高系统吞吐量。仿真分析表明,所提算法具有更高的吞吐量,比最大吞吐量算法和Gong算法提高了13.52%和5.61%,能够满足用户的最低速率要求。Aiming at the resource allocation problem of broadband power line carrier communication,a physical layer resource allocation algorithm is proposed to meet the needs of low complexity.Firstly,based on the equal power allocation method,the set of sub-carriers re-quired by each user to meet the minimum rate requirements is determined.The multi-user problem in resource allocation can be split in-to single-user problems is determined the optimal power allocation.Then Lagrange Multiplier Method is used to optimize the power of the sub-carrier set used by each user to further improve the system throughput.Simulation analysis shows that the proposed algorithm has higher throughput,and it is 13.52%and 5.61%higher than the maximum throughput algorithm and the Gong algorithm respectively,meeting the minimum rate requirements of users.
