Hi
We have two FIR Filters, running on same input data, generated for different purposes.

Wisnumurti Kristanto - Sep 30 2008
Hi Jawaad,
Maybe you can just sample your image in 3x3 matrix ?
For example you have matrix:
A = 300 x 300 matrix
you can sample it by take:
a1 = A(1:3,1:3);
a2 = A(1:3,4:6... simulation of ofdm with QPSK in Rayleigh channel
