摘要
串扰是影响数字用户线路(DSL)系统性能的一个主要问题。动态频谱管理技术(DSM)是处理DSL宽带传输过程中信道串扰的关键技术。基于DSL的DSM算法有很多种,如:注水算法(IW)、迭代谱均衡算法(OSB)、最优谱均衡算法(ISB)等。这里主要介绍了DSM的模型和几种DSM算法,并比较了它们的复杂度和性能。
Crosstalk is the limiting factor of perfor- mance in Digital Subscriber Line systems, the Dy- namic Spectrum Management (DSM) has been rec- ognized as a key technology for tackling multi-user crosstalk interference in DSL broadband access. There are several algorithms of DSM for DSL such as IW, OSB, ISB and so on. They are campared in terms of performance and computational complexity.
