Abstract:
(EN) This disclosure provides systems and methods for randomizing output transmissions in a Discrete Fourier Transform-Spread-OFDM (DFT-S-OFDM) system. An output signal is pseudo-randomized using spreading or repeating and scrambling to increase coverage range of user equipment (UE) and reduce the effects of interference to other UEs, thereby providing a more robust multiuser network.
(FR) La présente invention concerne des systèmes et des procédés de randomisation de transmissions de sortie dans un système de multiplexage par répartition orthogonale de fréquence avec étalement par transformée de Fourier discrète (DFT-S-OFDM). Un signal de sortie est pseudo-randomisé par intervention d'un étalement ou d'une répétition et d'un embrouillage pour augmenter la plage de couverture d'un équipement d'utilisateur (UE) et réduire les effets d'interférence pour d'autres UE, ce qui permet d'obtenir un réseau multi-utilisateur plus robuste.
