Coherent averaging for measuring traveling wave tube amplifier nonlinearity |
摘要 |
A method and system provide the ability to measure a transmission performance characteristic. A signal is received and demodulated. An ideal signal is generated from the demodulated signal. The received signal is coherently averaged to reduce noise. The performance characteristic is the estimated TWTA nonlinearity from a difference between the coherently averaged ideal signal and received signal.
