- W2349840154 abstract "The arithmetic Fourier transform(AFT) is a very important Fourier analysis technique.AFT needs only O(N) multiplications and has simple computational structure,so it is very suitable for VLSI design.It arises in many applications.But AFT needs many additions ( O(N 2 )),so it is very important to reduce its number of additions.By analyzing sampling characteristics of AFT,this paper gives improved algorithms of AFT for odd and even functions,and based on these algorithms,gives an improved AFT algorithm for general functions.The improved algorithms reduce the numbers of additions of AFT algorithms to a half and increase the computational speeds to double.The improved AFT algorithms for even and odd functions can also be used for computing discrete cosine transform (DCT) and discrete sine transform (DST),respectively." @default.
