USE PEAK FASTER TO CHARACTERIZE POWER-AMPLIFIERS

MULTICARRIER and spread-spectrum systems generate in-band and out-of-b and intermodulation (WI) spectra due to nonlinearities in components s uch as amplifiers. To ensure that IEA spectra do not violate interfere nce standards or degrade system performance, designers must be well-ve rsed in the statistical properties of multicarrier and spread-spectrum signals, Among the parameters used to describe cellular, code-divisio n-multiple-access (CDMA), and cable-television (CATV) signals are inst antaneous peak-power factor (IPF), envelope peak factor (EPF), and ave rage power.
