The performance of the proposed complex-valued Lyapunov adaptive filter (CLAF) algorithm is improved for the complex-valued system identification problem by integrating the LST into the filter optimization cost. The performance of the proposed algorithm is tested on a complex-valued moving average (MA) system identification problem and compared with the conventional complex-valued least mean square (CLMS) and complex-valued normalized least mean square (CNLMS) algorithms. The simulation results show that the proposed CLAF algorithm has achieved a faster convergence rate and a lower steady-state MSE performance when compared to the other algorithms. © 2015 Chamber of Electrical Engineers of Turkey.enAdaptive filtersBandpass filtersOptimizationReligious buildingsComplex domainsFaster convergenceFilter algorithmFilter optimizationLeast mean squaresLyapunov stability theoryNormalized least mean squareSystem identification problemsAlgorithmsConference Object10.1109/ELECO.2015.7394557124112442-s2.0-84963829038N/A
