Study of Robust Adaptive Beamforming Based on Low-Complexity DFT Spatial Sampling
Saeed Mohammadzadeh, Vitor H. Nascimento, Rodrigo C. de Lamare +1
In this paper, a novel and robust algorithm is proposed for adaptive beamforming based on the idea of reconstructing the autocorrelation sequence (ACS) of a random process from a s…
Low-Cost Maximum Entropy Covariance Matrix Reconstruction Algorithm for Robust Adaptive Beamforming
S. Mohammadzadeh, V. H. Nascimento, R. C. de Lamare
In this letter, we present a novel low-complexity adaptive beamforming technique using a stochastic gradient algorithm to avoid matrix inversions. The proposed method exploits algo…
Joint Model-Order and Step-Size Adaptation using Convex Combinations of Adaptive Reduced-Rank Filters
Rodrigo C. de Lamare, Vitor H. Nascimento
In this work we propose schemes for joint model-order and step-size adaptation of reduced-rank adaptive filters. The proposed schemes employ reduced-rank adaptive filters in parall…
