Study of Mixed-Integer Optimization Based on Graph-Based Decomposition for Cell-Free Networks
Julio Cesar Cardoso Tesolin, Rodrigo C. de Lamare
This letter develops a radio access network (RAN) framework for mixed discrete-continuous optimization problems that arise in user-centric cell=free massive multiple-antenna networ…
Study of Graph-Based Search for Energy-Efficient Clustering in Cell-Free Massive MIMO Networks
Julio Cesar Cardoso Tesolin, Rodrigo C. de Lamare
This paper investigates energy-efficient clustering in user-centric cell-free massive MIMO networks, addressing the access point clustering and power allocation problems via a mixe…
Study of Switched Step-size Based Filtered-x NLMS Algorithm for Active Noise Cancellation
Zhiyuan Li, Yi Yu, Hongsen He +2
While the filtered-x normalized least mean square (FxNLMS) algorithm is widely applied due to its simple structure and easy implementation for active noise control system, it faces…
Study of Adaptive Reliability-Driven Conditional Innovation Decoding for LDPC Codes
Hassan Touati, Rodrigo C. de Lamare
In this work, we present an adaptive reliability-driven conditional innovation (AR-CID) decoding algorithm for low-density parity check (LDPC) codes. The proposed AR-CID decoding a…
Direction Finding with Sparse Arrays Based on Variable Window Size Spatial Smoothing
Wesley S. Leite, Rodrigo C. de Lamare, Yuriy Zakharov +2
In this work, we introduce a variable window size (VWS) spatial smoothing framework that enhances coarray-based direction of arrival (DOA) estimation for sparse linear arrays. By c…
Study of Cluster-Based Routing Based on Machine Learning for UAV Networks in 6G
Luis Antonio L. F. da Costa, Rodrigo C. de Lamare, Rafael Kunst +1
The sixth generation (6G) wireless networks are envisioned to deliver ultra-low latency, massive connectivity, and high data rates, enabling advanced applications such as autonomou…
