Abstract
(EN)
A transmitting apparatus (10) according to the present invention is provided with: a symbol generation unit (1) that generates N symbols when N is an integer greater than or equal to two; a time-frequency conversion unit (2) that converts the N symbols into an N-point frequency domain signal; a band limiting filter (3) that generates an ND-point frequency domain signal, ND being smaller than N, by performing bandwidth limitation on the N-point frequency domain signal; an interpolation-processing and frequency-time conversion unit (4) that converts the ND-point frequency domain signal into a time domain signal; and a transmitting unit (6) that transmits the time domain signal at set transmission intervals.
(FR)
La présente invention concerne un appareil d'émission (10) qui comporte : une unité de génération de symbole (1) qui génère N symboles lorsque N est un nombre entier supérieur ou égal à deux ; une unité de conversion temps-fréquence (2) qui convertit les N symboles en un signal de domaine fréquentiel à N points ; un filtre de limitation de bande (3) qui génère un signal de domaine fréquentiel à ND points, ND étant plus petit que N, par réalisation d’une limitation de bande passante sur le signal de domaine fréquentiel à N points ; une unité de traitement d’interpolation et de conversion fréquence-temps (4) qui convertit le signal de domaine fréquentiel à ND points en un signal de domaine temporel ; et une unité d'émission (6) qui émet le signal de domaine temporel à des intervalles d'émission réglés.
