For example, 8×8 DFT matrix data making prescribed element data a complex number are given to a data compression part 4 from a DFT processing part 2 as 2n×2m DFT matrix data. In this case, the part 4 removes each element data corresponding to F(2n-k1, 0), F(0, 2m-k2), F(2n...

A simple way to expedite the process of DFT calculation is to use matrix manipulation instead of a “for loop”.This is shown below. clear all close all fm=100; fs=1000; Ts=1/fs; N=128; t=0:Ts:(N-1)*Ts; x=cos(2*pi*fm*t); ...
