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…
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…
Computation-Limited Signals: A Channel Capacity Regime Constrained by Computational Complexity
Saulo Queiroz, João P. Vilela, Edmundo Monteiro
In this letter, we introduce the computational-limited (comp-limited) signals, a communication capacity regime in which the signal time computational complexity overhead is the key…
