Multicarrier modulation is a powerful transmission technique that provides improved
performance in various communication fields. A fundamental topic of multicarrier …

The mutual information of independent parallel Gaussian-noise channels is maximized,
under an average power constraint, by independent Gaussian inputs whose power is …

In Part I of this work, we introduced multiconductor-transmission-line (MTL) theory to model
the indoor power-line (PL) channel. We have also shown that the proposed MTL approach …

In this two-part paper, we address the problem of finding the optimal precoding/multiplexing
scheme for a set of noncooperative links sharing the same physical resources, eg, time and …

Adaptive OFDM has the potential of providing bandwidth-efficient communications in hostile
propagation environments. Currently, bit loading algorithms use M-ary quadrature amplitude …

This letter presents a new bit-loading algorithm for discrete multitone systems that converges
faster to the same bit allocation as the optimal discrete bit-filling and bit-removal methods …

An alternative implementation of the filter bank multicarrier (FBMC) concept is introduced. It
is based on an FFT whose size is the length of the prototype filter. The approach clarifies the …

For parallel independent Gaussian-noise channels with an aggregate power constraint,
independent Gaussian inputs whose powers are allocated according to the waterfilling …

This letter considers optimum linear transceivers for MIMO channels under a general
framework based on Schur-concave and Schur-convex cost functions, subject to shaping …

In this paper, we develop and test new algorithms for the optimal discrete bit-loading of
digital subscriber loop (DSL) multicarrier (MC) systems when constraints on both the total …
