| Abstract: | This paper presents a new technique for reducing the 'Near–Far' problem with modified IWF algorithm by using the fixed spectral mask yielding improved data rate of near end user. It is shown through graphical results that the proposed technique for spectrum management achieves a significant gain in data rate for two users very high speed digital subscriber line network compared to that of traditional Iterative Water filling (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 OSB algorithm. [ABSTRACT FROM AUTHOR] |
