Özet:

 

We investigated adaptive algorithms for a Hammerstein block structure in   which a static nonlinear block and dynamic linear block are cascaded. The   approach considered here is to use generalized orthonormal basis functions   in a Hammerstein block structure by using fixed pole filter banks. We   applied the normalized least mean square approach to the developed adaptive   algorithm in order to acquire Hammerstein block structure parameters.   Performance comparison of the proposed approach was investigated considering   convergence speed and parametric complexity for acoustic echo cancellation   application. The results indicated that in the developed algorithm along   with appropriate selection of fixed poles, the algorithm convergences faster   and less parametric complexity is provided when compared to direct adaptive   Hammerstein algorithms with IIR and FIR linear blocks.
