Is FFT Fast Enough for Beyond-5G Communications?
Saulo Queiroz, João P. Vilela, Edmundo Monteiro
In this paper, we study the impact of computational complexity on the throughput limits of the {\color{black}fast Fourier transform (FFT)} algorithm for {\color{black}orthogonal fr…
Optimal Mapper for OFDM with Index Modulation: A Spectro-Computational Analysis
Saulo Queiroz, João P. Vilela, Edmundo Monteiro
In this work, we present an optimal mapper for OFDM with index modulation (OFDM-IM). By optimal we mean the mapper achieves the lowest possible asymptotic computational complexity…
Maximal Spectral Efficiency of OFDM with Index Modulation under Polynomial Space Complexity
Saulo Queiroz, Wesley Silva, João P. Vilela +1
In this letter, we demonstrate a mapper that enables all waveforms of OFDM with Index Modulation (OFDM-IM) while preserving polynomial time and space computational complexities. En…
