This paper considers the problem of digital predistortion of parallel Wiener-type systems using the recursive prediction error method (RPEM) and the nonlinear filtered-x least mean squares (NFxLMS) algorithms. The RPEM algorithm is used for the identification of the parallel Wiener-type system and the FIR filter that represents the inverse of the linear kernels. Then the estimate of the nonlinear...
Adaptive predistortion of nonlinear systems described using IIR Hammerstein models is introduced in this paper. The adaptive predistorter is modeled as an IIR Wiener system. The parameters of the linear and nonlinear blocks of the predistorter are estimated simultaneously using the nonlinear filtered-x least mean squares (NFxLMS) algorithm. The NFxLMS algorithm is derived under the assumption that...
