Abstract :
The basic subject of this paper is devoted to the construction, realization and investigations of two algorithms for Fourier transform vector quantization design procedure. The first one is based on the quantization of real and imaginary parts and the second on the magnitude and phase parts of the FFT result. Achievements in the area of data compression in both cases are discussed
