Convex optimization methods are widely used in the design and analysis of communication
systems and signal processing algorithms. This tutorial surveys some of recent progress in …

A wide variety of resource management problems of recent interest, including power/rate
control, link scheduling, cross-layer control, network utility maximization, beamformer design …

The design and optimization of multicarrier communications systems often involve a
maximization of the total throughput subject to system resource constraints. The optimization …

Consider a communication system whereby multiple users share a common frequency band
and must choose their transmit power spectral densities dynamically in response to physical …

In cognitive radio (CR) networks, there are scenarios where the secondary (lower priority)
users intend to communicate with each other by opportunistically utilizing the transmit …

We propose a novel decomposition framework for the distributed optimization of general
nonconvex sum-utility functions arising naturally in the system design of wireless multi-user …

Dynamic spectrum management of digital subscriber lines (DSLs) has the potential to
dramatically increase the capacity of the aging last-mile copper access network. This paper …

Transmit power in wireless cellular networks is a key degree of freedom in the management
of interference, energy, and connectivity. Power control in both the uplink and downlink of a …

This paper considers a wireless cooperative cellular data network with a base station and
many subscribers in which the subscribers have the ability to relay information for each other …

In this paper, we develop a unified framework for linear nonregenerative multicarrier multiple-
input multiple-output (MIMO) relay communications in the absence of the direct source …
