Abstract :
It has previously been claimed that a class of filter banks called the principal component filter banks (PCFB) is optimal for digital communication using discrete multitone modulation. In this paper we revisit this result and examine the origin of this optimality. We provide illustrative examples comparing the PCFB with traditional filters. We also provide a rigorous proof of the claim that the bit rate is maximized by the PCFB
