Abstract :
The authors study the behavior of the partial correlation (PARCOR) coefficients of the stochastic gradient adaptive lattice filter in response to a complex linear chirp FM signal in white Gaussian noise. A single-stage model for the behavior of the coefficients is developed, and the recovery error is derived. Also, an accurate model for a two-stage filter is derived
