Statistical Measurements

ABSTRACT: RF power measurements are a staple of wireless technological development, proving essential in fundamental design aspects such as performance, regulatory standard fulfillment, and safety specification compliance. In modern communications using digital modulation methods like OFDM with a noise like-like appearance in the time domain, typical characterizations like average power measurements are often insufficient to fully characterize the signals. Therefore, peak power and statistical measurements have become a useful and more effective way to analyze these signals. Among the variety of statistical measurements to depict digitally modulated signals, the complementary cumulative distribution function (CCDF) and underlying crest factor measurements are effective tools that yield important information for accurate signal characterization.
