This paper considers the problem of downlink transmit beamforming for wireless
transmission and downstream precoding for digital subscriber wireline transmission, in the …

Recent theoretical results describing the sum-capacity when using multiple antennas to
communicate with multiple users in a known rich scattering environment have not yet been …

The effective operation of distributed energy sources relies significantly on the
communication systems employed in microgrids. This article explores the fundamental …

This paper characterizes the sum capacity of a class of potentially nondegraded Gaussian
vector broadcast channels where a single transmitter with multiple transmit terminals sends …

The performance of DSL systems is severely constrained by crosstalk due to the
electromagnetic coupling among the multiple twisted pairs making up a phone cable. In …

Crosstalk is a major issue in modern digital subscriber line (DSL) systems such as ADSL
and VDSL. Static spectrum management, which is the traditional way of ensuring spectral …

Multiple-input multiple-output (MIMO) channels provide an abstract and unified
representation of different physical communication systems, ranging from multi-antenna …

In recent years, considerable attention has been paid to the joint optimal transceiver design
for multi-input multi-output (MIMO) communication systems. In this paper, we propose a joint …

(Preliminary): The Orthogonal Frequency Division Multiplexing (OFDM) digital transmission
technique has several advantages in broadcast and mobile communications applications …

We study the problem of power efficient multiuser beamforming transmission for both uplink
and downlink. The base station is equipped with multiple antennas, whereas the mobile …
