hi.. can any one pls help me in finding the signal frequency in digital ifm receiver.. following r the equations to find.. first has to fine the zone mapping thn has to find the frequency
f1=θ*fs/(2*m1*pi) where θ=phase, m=signal samples.here m=1,2,8,32,128 and fs=2.56e9Hz. this is for finding first frequency and for finding zone and other the equations goes like this.. zm=floor(m*f(m-1))/fs, this id finding for zone and for other frequencis the eq is fm=(fs/(2*pi))*(θm/m+zm*(2*pi/m)). i hav written the code but m getting error has in only .5mhz but i should get it within +2MHz to -2MHz for every 100ns
