Study of searching the optimal fractional Fourier transform order based on quasi-Newton method

Chen Rong;Ma Juhong;School of Urban Rail Transportation,Soochow University;Library of Jiangsu University of Science and Technology;  
To realize effective searching of the optimal fractional Fourier transform order,this paper analyzes the basic principle of quasi-Newton method. The implementation steps of quasi-Newton method are studied specifically. Simulation presents the converging process of searching the optimal fractional Fourier transform order based on quasi-Newton method. The advantages and disadvantages of this method are discussed.
