Do Proportionate Algorithms Exploit Sparsity?
Markus V. S. Lima, Gabriel S. Chaves, Tadeu N. Ferreira +1
Adaptive filters exploiting sparsity have been a very active research field, among which the algorithms that follow the "proportional-update principle", the so-called proportionate…
Joint AGC and Receiver Design for Large-Scale MU-MIMO Systems Using Low-Resolution Signal Processing in C-RANs
T. Cunha, R. C. de Lamare, T. N. Ferreira +1
Large-scale multi-user multiple-input multiple-output (MU-MIMO) systems and cloud radio access networks (C-RANs) are considered promising technologies for the fifth generation (5G)…
Joint AGC and Receiver Design for Large-Scale MU-MIMO Systems with Coarsely Quantized Signals and C-RANs
T. Cunha, R. C. de Lamare, T. N. Ferreira
In this work, we propose the joint optimization of the automatic gain control (AGC), which works in the remote radio heads (RHHs), and a low-resolution aware (LRA) linear receive f…
Efficient Steered-Response Power Methods for Sound Source Localization Using Microphone Arrays
Markus V. S. Lima, Wallace A. Martins, Leonardo O. Nunes +4
This paper proposes an efficient method based on the steered-response power (SRP) technique for sound source localization using microphone arrays: the volumetric SRP (V-SRP). As co…
