Robust Adaptive Beamforming Algorithms Based on the Constrained Constant Modulus Criterion
L. Landau, R. C. de Lamare, M. Haardt
We present a robust adaptive beamforming algorithm based on the worst-case criterion and the constrained constant modulus approach, which exploits the constant modulus property of…
Low-Complexity Design of Generalized Block Diagonalization Precoding Algorithms for Multiuser MIMO Systems
K. Zu, R. C. de Lamare, M. Haardt
Block diagonalization (BD) based precoding techniques are well-known linear transmit strategies for multiuser MIMO (MU-MIMO) systems. By employing BD-type precoding algorithms at t…

Keke Zu, Rodrigo C. de Lamare, Martin Haardt
Low-complexity precoding {algorithms} are proposed in this work to reduce the computational complexity and improve the performance of regularized block diagonalization (RBD) {based…
Frequency-Domain Group-based Shrinkage Estimators for UWB Systems
Sheng Li, Rodrigo C. de Lamare, Martin Haardt
In this work, we propose low-complexity adaptive biased estimation algorithms, called group-based shrinkage estimators (GSEs), for parameter estimation and interference suppression…
Sum-Rate Maximization with Minimum Power Consumption for MIMO DF Two-Way Relaying: Part I - Relay Optimization
Jie Gao, Sergiy A. Vorobyov, Hai Jiang +2
The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay.…
Blind Adaptive Constrained Constant-Modulus Reduced-Rank Interference Suppression Algorithms Based on Interpolation, Switched Decimation and Filtering
Rodrigo C. de Lamare, Raimundo Sampaio-Neto, Martin Haardt
This work proposes a blind adaptive reduced-rank scheme and constrained constant-modulus (CCM) adaptive algorithms for interference suppression in wireless communications systems.…
