The present invention discloses methods and systems of measuring transmission performance characteristics, such as from an amplifier. The method comprises the steps of receiving a signal, demodulating the signal, generating an ideal signal from the demodulated signal and estimating the performance characteristic from a difference between the ideal signal and the received signal. A system for measuring a transmission performance characteristic, comprises a demodulator (202) for demodulating a received signal, a signal generator (204) for producing an ideal signal (220) from the demodulated signal and a processor (118) for estimating the performance characteristic from a difference between the ideal signal and the received signal.
Cette invention a trait à des procédés, ainsi qu'aux systèmes correspondants, permettant de mesurer des caractéristiques d'émission, celles d'un amplificateur notamment. Le procédé consiste à recevoir un signal, à le démoduler, à produire un signal idéal et à estimer les caractéristiques de fonctionnement d'après une différence existant entre le signal idéal et le signal reçu. Le système à cet effet comporte un démodulateur (202) démodulant un signal reçu, un générateur de signal (204) produisant un signal idéal (220) à partir du signal démodulé et un processeur (118) servant à estimer les caractéristiques de fonctionnement d'après la différence existant entre le signal idéal et le signal reçu.
