Title (EN) TRANSMIT AMPLITUDE AND PHASE MODULATION BASED ON TWO CONSTANT-AMPLITUDE PHASORS
(FR) MODULATION D’AMPLITUDE ET DE PHASE D’ÉMISSION SUR LA BASE DE DEUX PHASEURS À AMPLITUDE CONSTANTE
Abstract:
(EN) Techniques for generating signals based on two constant amplitude phasors are discussed. One example apparatus includes phase calculation circuitry that generates first and second angles from a representation of a complex signal; distributor circuitry that receives the second angle and outputs a positive and a negative version of it; a first signal generator configured that receives the first angle and one of the positive or the negative version and generates a first signal based on the first angle and the one of the positive or the negative version; a second signal generator that receives the first angle and the other of the positive or the negative version and generates a second signal based on the first angle and the other of the positive or the negative version; and a combiner that combines the first and the second signal and generates an output signal equivalent to the complex signal.
(FR) L’invention aborde des techniques de génération de signaux à base de deux phaseurs à amplitude constante. Un appareil illustratif inclut des circuits de calcul de phase qui génèrent de premier et deuxième angles depuis une représentation d’un signal complexe ; des circuits distributeurs qui reçoivent le deuxième angle et émettent une version positive et une version négative du deuxième angle ; un premier générateur de signal configuré qui reçoit le premier angle et une version parmi la version positive ou la version négative et qui génère un premier signal sur la base du premier angle et de ladite version parmi la version positive ou de la version négative ; un deuxième générateur de signal qui reçoit le premier angle et l’autre version parmi la version positive ou la version négative et qui génère un deuxième signal sur la base du premier angle et de ladite autre version parmi la version positive ou de la version négative ; et un combineur qui combine le premier et le deuxième signal et qui génère un signal de sortie équivalent au signal complexe.
