Description
A Complementary Cumulative Distribution Function (CCDF) plot displays how much time the signal "spends" at or above a power level. Plotted in percentage of time, the CCDF curve presents relative power levels versus probability. Since the modern digitally modulated signals might have significant Peak-to-Average-Power level, the CCDF curve can be used for estimation of the signal compression caused by the Amplifier.
