Indoor Radio Channel (2GHz)
Indoor Radio Channel (2GHz)
(OP)
During an experiment we measure the amplitude of a signal and its phase.Some files were produced.After that we plot the values amplitude-freq and phase-freq.Now i have to apply the auto correlation on each frequency in order to calculate the coherence bandwidth using matlab. The textbooks are not very helpful.Is anybody can give me some hints?





RE: Indoor Radio Channel (2GHz)
Cf,g(u)=Hf,g(u)/[Hf(0) x Hg(0)]**0.5
with property of:
-1 <=Cf,g(u)<=+1 for all u
where
Hf,g=integral from -infinity to +infinity of [f(t)g(t-u)]dt=integral from -infinity to +infinity of [f(t-u)g(t)]dt
and
Hf(u)=integral from -infinity to +infinity of [f(t)f(t+u)]dt=integral from -infinity to +infinity of [(f(t-u)f(t)]dt
Hg(u)=integral from -infinity to +infinity of [g(t)g(t+u)]dt=integral from -infinity to +infinity of [g(t-u)g(t)]dt
