<p>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.</p> |
