output_of_DCT_in_image_fusion
u can calculate DCT
clc
inp = imread( Im1.jpg )
inp1 = imread( Im2.jpg )
A = double(inp(:,:,1))
B = double(inp1(:,:,1))
A1=double(blkproc(A,[8 8], dct2 ))
B1=double(blkproc(B,[8 8], dct2 ))
[r,c] = size(A1)
r1 = []
for i=1:r
for j=1:c
if A1(i,j) > B1(i,j)
r1(i,j)=A1(i,j)
else
r1(i,j)=B1(i,j)
end
end
end
r1= double(r1(:,:,1))
C=blkproc(r1,[8 8], idct2 )
round(C)
C1=idct2(r1)

QPSK_TX_IQ_RX_REV1
QPSK Transmitter and I/Q Correlator Receiver is based on the technique of queing the information in a bit stream and on the receving end using FFT and some additive filters, as the addition of noise is made to infuse the need of a filter. Necessarily a Baseband filter is used. Modulation acheived at the receiving end.
