We consider the downlink throughput maximization problem for interference limited
multiuser systems. Our goal is to characterize the optimum base station transmission …

We consider the problem of weighted sum-rate maximization in a multicell downlink system.
The problem is NP-hard and therefore difficult to solve, even in a centralized manner. We …

Intercell interference is a major limiting factor in wireless multi-cell networks. Recently, it has
been shown that significant performance gains can be achieved by cooperation between …

In this paper, we propose a downlink transmission strategy based on intercell interference
pricing and a distributed algorithm that enables each base station (BS) to design locally its …

The control and reduction of multiuser interference is a fundamental problem in wireless
communications. In order to increase the spectral efficiency and to provide individual quality …

We propose a joint approach for multiuser receiver design and power allocation. Inter-user
interference is modeled by an axiomatic framework, based on parameter-dependent …

We study in this paper optimal signaling for downlink transmission with mutual interference.
Restricting each receiver to a single user detector, we show that computing the achievable …

To maximize the downlink code-division multiple access (CDMA) system capacity, we
propose to minimize the total transmitted power of the system subject to users′ signal-to …

We consider a multiuser system where a single transmitter equipped with multiple antennas
(the base station) communicates with multiple users each with a single antenna …

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 …
