Direction of Arrival Estimation with Sparse Subarrays
W. Leite, R. C. de Lamare, Y. Zakharov +2
This paper proposes design techniques for partially-calibrated sparse linear subarrays and algorithms to perform direction-of-arrival (DOA) estimation. First, we introduce array ar…
Study of filtered-x logarithmic recursive least -power algorithm
Z. Zheng, L. Lu, Y. Yu +2
For active impulsive noise control, a filtered-x recursive least -power (FxRLP) algorithm is proposed by minimizing the weighted summation of the -power of the \emph{a poster…
A survey on active noise control techniques -- Part I: Linear systems
Lu Lu, Kai-Li Yin, Rodrigo C. de Lamare +4
Active noise control (ANC) is an effective way for reducing the noise level in electroacoustic or electromechanical systems. Since its first introduction in 1936, this approach has…
Study of List-Based OMP and an Enhanced Model for Direction Finding with Non-Uniform Arrays
W. S. Leite, R. C. de Lamare
This paper proposes an enhanced coarray transformation model (EDCTM) and a mixed greedy maximum likelihood algorithm called List-Based Maximum Likelihood Orthogonal Matching Pursui…
Study of Robust Two-Stage Reduced-Dimension Sparsity-Aware STAP with Coprime Arrays
X. Wang, Z. Yang, J. Huang +1
Space-time adaptive processing (STAP) algorithms with coprime arrays can provide good clutter suppression potential with low cost in airborne radar systems as compared with their u…
Study of Distributed Robust Beamforming with Low-Rank and Cross-Correlation Techniques
H. Ruan, R. C. de Lamare
In this work, we present a novel robust distributed beamforming (RDB) approach based on low-rank and cross-correlation techniques. The proposed RDB approach mitigates the effects o…
Study of Channel Estimation with Oversampling for 1-bit Large-Scale MIMO Systems
Z. Shao, L. Landau, R. de Lamare
In this paper, we propose an oversampling based low-resolution aware least squares channel estimator for large-scale multiple-antenna systems with 1-bit analog-to-digital converter…
Study of Robust Distributed Beamforming Based on Cross-Correlation and Subspace Projection Techniques
H. Ruan, R. C. de Lamare
In this work, we present a novel robust distributed beamforming (RDB) approach to mitigate the effects of channel errors on wireless networks equipped with relays based on the expl…
