Computation-Limited Signals in Practice: A Throughput Anomaly in Software-Defined O-RAN PHY Layers
Gabriel Alessi Posonski, Saulo Queiroz, João P. Vilela +3
We formalize a performance anomaly in software-based wireless physical-layer (PHY) implementations, a key enabling technology for Open Radio Access Network (O-RAN) systems. For a f…

Fast Computation of the Discrete Fourier Transform Rectangular Index Coefficients
Saulo Queiroz, João P. Vilela, Benjamin Koon Kei Ng +2
In~\cite{sic-magazine-2025}, the authors show that the square index coefficients (SICs) of the -point discrete Fourier transform (DFT) -- that is, the coefficients $X_{k\sqrt{N}…

Computational Complexity-Constrained Spectral Efficiency Analysis for 6G Waveforms
Saulo Queiroz, João P. Vilela, Benjamin Koon Kei Ng +2
In this work, we present a tutorial on how to account for the computational time complexity overhead of signal processing in the spectral efficiency (SE) analysis of wireless wavef…
