Abstract :
A study of noise power ratio (NPR) of real communication signals is performed. The analysis of NPR is done using the orthogonalization of the behavioral model which allows the separation of the correlated and uncorrelated components of the nonlinear output. It is shown that NPR measurements using NBGN overestimate in-band distortion of real communication signals. Simulated NPR of a reverse link IS-95 signal is compared to that of narrow band Gaussian noise (NBGN) and verified by measurements.
