Discrete multitone communication with principal component filter banks
نویسندگان
چکیده
It has recently 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.

Optimality of principal component filter banks for discrete multitone communication systems
Discrete multitone modulation is an attractive method for communication over a non flat 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, ar...

متن کاملA Review of the Theory and Applications of Optimal Subband and Transform Coders
The problem of optimizing digital filter banks based on input statistics was perhaps first addressed nearly four decades ago by Huang and Schultheiss. These authors actually considered a special case, namely transform coder optimization. Many of the subband coder optimization problems considered in recent years have close similarities to this work, though there are fundamental differences as we...
متن کاملFilter Banks in Digital Communications
Digital signal processing has played a key role in the development of telecommunication systems over the last two decades. In recent years digital filter banks have been occupying an increasingly important role in both wireless and wireline communication systems. In this paper we review some of these applications of filter banks with special emphasis on discrete multitone modulation which has h...
متن کاملOptimum design of overlapping discrete multitone filter banks for digital subscriber line channels
In this paper, a new approach to the design of optimum transmultiplexer filter banks for overlapping discrete multitone (ODMT) multicarrier modulation is presented. ODMT has been proposed for use in high-speed data communications over twistedpair copper wires such as digital subscriber lines (DSL), due to its ability to cope well with channel degradations and noise. In this study we propose a n...
