Abstract:
Crosscorrelation using a binary MLS excitation yields a linear system response, whereas system nonlinearity produces a residue dispersed over the MLS period. By incorporating precomputed templates, coefficients of a nonlinear polynomial descriptor can be decoded from this distortion residue, and, by incorporating complex coefficients, nonlinearity with memory can be accommodated. A nonlinear model results from which general THD and IMD can be derived from a single MLS measurement
