Abstract:
(EN) According to an aspect, there is provided a method for power-amplification of a transmission signal, comprising: obtaining the transmission signal with phase and amplitude modulation; generating a power-amplified polar signal for approximating a power-amplified transmission signal by power-amplifying a first constant-envelope signal with one of two or more first amplification factors based on the transmission signal; generating an outphasing pair of a first power-amplified outphasing signal and a second power-amplified outphasing signal based on the transmission signal; and combining the power-amplified polar signal, the first power-amplified outphasing signal and the second power-amplified outphasing signal to provide the power-amplified transmission signal.
(FR) Selon un aspect, l'invention concerne un procédé d'amplification de puissance d'un signal d'émission, consistant à : obtenir le signal d'émission avec modulation de phase et d'amplitude; générer un signal polaire amplifié en puissance pour approximer un signal d'émission amplifié en puissance par amplification de puissance d'un premier signal d'enveloppe constante avec un facteur d'amplification parmi au moins deux premiers facteurs d'amplification sur la base du signal d'émission; générer une paire de déphasage d'un premier signal de déphasage amplifié en puissance et d'un second signal de déphasage amplifié en puissance sur la base du signal d'émission; et combiner le signal polaire amplifié en puissance, le premier signal de déphasage amplifié en puissance et le second signal de déphasage amplifié en puissance pour fournir le signal d'émission amplifié en puissance.
