A novel technique to reduce Near-Far problem in multi-user VDSL network

In this paper, the proposed algorithm based on a novel technique for lowering the Near-Far problem in very high-speed digital subscriber line (VDSL) networks is presented. Through graphical results, it is demonstrated that the proposed technique performs better in terms of data rate for multi-user VDSL networks than the conventional IWF algorithm and comes close to the extremely complex OSB algorithm. The suggested algorithm’s complexity is comparable to that of the standard iterative water filling (IWF) algorithm and significantly less than that of the centralized optimal spectrum balancing (OSB) algorithm.
