Pre-Characterization of Electromagnetic Side-Channel Leakage Using Publicly Available Information: A Case Study on E-Voting Interfaces
Leonardo Teodoro, Kemuel L. Vieira, Saulo Queiroz
In this work, we study the interface of the Brazilian e-Voting Machine (BVM) in the context of electromagnetic side-channel threats commonly referred to as TEMPEST attacks. In a TE…
Fast Compressed-Domain N-Point Discrete Fourier Transform: The "Twiddless" FFT Algorithm
Saulo Queiroz
In this work, we present the \emph{twiddless fast Fourier transform (TFFT)}, a novel algorithm for computing the -point discrete Fourier transform (DFT). The TFFT's divide strat…
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…
Fast Computation of the Discrete Fourier Transform Square Index Coefficients
Saulo Queiroz, João P. Vilela, Edmundo Monteiro
The -point discrete Fourier transform (DFT) is a cornerstone for several signal processing applications. Many of these applications operate in real-time, making the computationa…
