Abstract(s) :

(Anglais) In this work, a literature review of filter-based waveforms proposed in the Digital Terrestrial Television (DTT) standard context improvement is presented. It also compares low complexity algorithms of Filter Bank Multicarrier (FBMC) and Universal Filtered Multicarrier (UFMC) applied to the next generation of Digital Video Broadcasting-Terrestrial, second generation (DVB-T2) system. As known, Orthogonal Frequency Division Multiplexing (OFDM) and both FBMC and UFMC have common characteristics like the use of Fast Fourier Transform (FFT) in their functional blocks diagram. However, the FBMC and UFMC are mainly based on different filtering operations, which induce a high implementation complexity but present a better performance in a broadcasting system when compared to the classical OFDM. Their computation complexity is studied to highlight the optimal low complexity algorithm. Furthermore, the compromise between FBMC and UFMC waveforms applied to DVB-T2 in terms of SNR performance gains, spectral efficiency, and complexity is established. This paper shows that UFMC is a good compromise as its complexity is reduced to the same complexity as OFDM while having advantages.
