Abstract

This paper presents a new technique for reducing the ‘Near–Far’ problem with modified iterative water filling (IWF) algorithm by using the adaptive power spectral mask yielding improved data rate of near end users in a VDSL network. It is shown through graphical results that the proposed technique for spectrum management achieves a significant gain in data rate for ten users VDSL network compared to that of traditional IWF algorithm. However, data rate of the proposed algorithm approaches near to highly complex optimal spectrum balancing (OSB) algorithm. The complexity of the proposed algorithm is same as that of IWF algorithm, which is much lower than that of highly complex OSB algorithm.
