英文摘要

      In this paper，a new identification technique is presented，which uses cyclic impulse signals with different amplitudes as input signals and has obtained strong consistence estimates of the unknown parameters of nonlinear gain and inpulse responses of linear subsystem of Wiener model. Moreover the paper also studies the asymptotic distributions of estimation errors，and has obtained the convergence speed of errors. Finally，simulation results show that the proposed method is very efficient and practical.
