Abstract :
This paper characterizes nonlinear distortion in an analog-to-digital converter (ADC) when excited by representative communication signals having non-constant time-domain envelopes. The effect of subjecting the ADC to signals that present a range of values of peak-to-average power ratio is studied in order to understand the impact of various nonlinear ADC mechanisms in the transmission chain.
