| 摘 要： | Aiming at the nonlinear system identification problem, a parallel recursive affine projection （AP） adaptive algorithm for the nonlinear system based on Volterra series is presented in this paper. The algorithm identifies in parallel the Volterra kernel of each order, recursively estimate the inverse of the autocorrelation matrix for the Volterra input of each order, and remarkably improve the convergence speed of the identification process compared with the NLMS and conventional AP adaptive algorithm based on Volterra ,series. Simulation results indicate that the proposed method in this paper is efficient.
