Selective Iterative Waterfilling for Digital Subscriber Lines
This paper presents a high-performance, low-complexity, quasi-distributed dynamic spectrum management (DSM) algorithm suitable for DSL systems. We analytically demonstrate that the rate degradation of the distributed iterative waterfilling (IW) algorithm in near-far scenarios is caused by the insufficient utilization of all available frequency and power resources due to its nature of noncoopera...
متن کاملAnalysis of Iterative Waterfilling Algorithm for Multiuser Power Control in Digital Subscriber Lines
In modern digital subscriber line (DSL) systems where multiple users must coexist in the same frequency band, multiuser power control is an effective technique for reducing crosstalk interference and improving total system throughput. The popular distributed iterative waterfilling algorithm (IWFA) for DSL power control lets each user locally measure the total noise plus interference powers in a...

متن کاملDistributed multiuser power control for digital subscriber lines
This paper considers the multiuser power control problem in a frequency-selective interference channel. The interference channel is modeled as a noncooperative game, and the existence and uniqueness of a Nash equilibrium are established for a two-player version of the game. An iterative water-filling algorithm is proposed to efficiently reach the Nash equilibrium. The iterative water-filling al...
