摘要

研究了混合非对称数字用户线路(ADSL) CO/RT部署中的动态频谱管理问题。提出了一种以扩大可达率区域为目标的分布式DSM算法。结果表明，与现有的分布式DSM迭代注水算法相比，新算法具有显著的性能提升。仿真结果还表明，该算法扩大了极高比特率数字用户线路(VDSL)系统上行传输的速率区域

Distributed Dynamic Spectrum Management Algorithm for Mixed ADSL CO/RT Deployments

This paper investigates the dynamic spectrum management (DSM) problem in mixed asymmetric digital subscriber line (ADSL) CO/RT deployments. A new distributed DSM algorithm is developed with an objective of enlarging the achievable rate region. The results show that the new algorithm achieves significant performance gains over the existing distributed DSM algorithm iterative water-filling (IW). Simulation results also show that the proposed algorithm enlarges the rate region in the upstream transmission of very-high bit-rate digital subscriber lines (VDSL) systems
