Absrract -A nonlinear spectral analysis technique that enables digital communication system metria; SNR, EVM and the waveform quality factor (p) to be related to in-band distortion spectrum is presented. System metrics are estimated from the measured output power and in-band distortion power. The estimated metrics are verified by direct measurements of each metric using a Vector Signal Analyzer (VSA) performed on a forward-link Is-95 signal. Estimated system met& are in excellent agreement with measured values.
