Abstract :
Discrete multitone modulation is an attractive method for communication over a nonflat channel with possibly colored noise. The uniform DFT filter bank and cosine modulated filter bank have in the past been used in this system because of low complexity. We show in this paper that principal component filter banks, which are known to be optimal for data compression and denoising applications, are also optimal for a number of criteria in DMT communication
