Title
(EN) NON-LINEAR-PHASE PULSE-SHAPE MINIMIZING SPURIOUS EMISSION AT POWER AMPLIFIER 2ND HARMONIC FOR BPSK SINGLE-CARRIER MODULATED SIGNAL
(FR) FORME D'IMPULSION À PHASE NON LINÉAIRE RÉDUISANT AU MINIMUM L'ÉMISSION PARASITE AU NIVEAU DE LA 2E HARMONIQUE D'UN AMPLIFICATEUR DE PUISSANCE POUR SIGNAL MODULÉ MONOPORTEUSE BPSK
Abstract
(EN)
A mobile network device or a User Equipment (UE) including a power amplifier, processing circuitry, and a filter can receive a radio frequency (RF) signal and perform a modulation of the RF signal into a modulated RF signal with a pulse-shaping that reduces even harmonic spurs. The pulse-shaping includes a time-domain modulation that comprises a single-carrier or a discrete Fourier transform (DFT) spread orthogonal frequency division multiplexing (DFT-s-OFDM). The pulse-shaping further reduces one or more narrow-band spurs based on an even harmonic distortion.
(FR)
Selon l'invention, un dispositif de réseau mobile ou un équipement utilisateur (UE) comprenant un amplificateur de puissance, un circuit de traitement et un filtre peuvent recevoir un signal radiofréquence (RF) et effectuer une modulation du signal RF en un signal RF modulé avec une mise en forme d'impulsions qui réduit les parasites d'harmoniques paires. La mise en forme d'impulsions comprend une modulation dans le domaine temporel qui comprend une modulation monoporteuse ou à multiplexage par répartition orthogonale de la fréquence (OFDM) à étalement par transformation de Fourier discrète (DFT) (DFT-s-OFDM). La mise en forme d'impulsions réduit en outre un ou plusieurs signaux parasites à bande étroite basés sur une distorsion d'harmoniques paires.
