Abstract
- This paper addresses spectral regrowth caused by wideband signals input into solid-state amplifiers. Unique contributions are a weighted least-squares method for solving predistorter nonlinear model parameters, and a Bayesian method for tracking model parameters in slowly changing systems. Next-generation active phased array radars are the primary application. Past predistortion research has been primarily aimed at narrowband communications, while radar wideband applications have been relatively unexplored. Laboratory measurements confirm our methods.
