does someone's know how do i change this code to ifft command? (the ifft part at the code) thanks!!
N=10;
fs=1e6;
T=1e-3;
% random signal
bit=randint(20,1); % 20 bits 0 or 1 1 x 20
% serial-to-parallel converter
par=reshape(bit,2,10); % 2 x 10 2 bits for sym
% mapper
sym=par'*[2;1]; % multiplay for mapper 00-0 01-1 10-2 11-3
phase=[-3*pi/4,3*pi/4,-pi/4,pi/4];
phase_sym=phase(sym+1); % every sym gets phase for example pi/4 will get '3'
_*
% IFFT
for k=0:N-1
i=1;
for t=1/fs:1/fs:T
x(k+1,i)=cos((2*pi*k*t)/T+phase_sym(k+1))+j*sin((2*pi*k*t)/T+phase_sym(k+1));
i=i+1;
end
end

Are you saying that instead of using a loop to perfrom IFFT you are interested in using ifft() ?
Is this what you mean ?

If you are looking to just find ifft then you can try the direct function available in Matlab ifft()
ifft(your signal/variable);
Hope this will help you
