5.5.2 Matched-filter type demodulator A Matched Filter (MF)to s(t)is defined as a LTI filter whose impulse response is as h()=Cs(T-1),where C is any non-zero constant and T is a given sample-time.. A MF tox(t) Sampling r() h(0)= y() y(T) MF is the optimal filter (T-) Compute, A matched filter is .0fr(rh-t)dr∫r(w[T equivalent to a correlator. An alternate demodulator S0, y(T=r(r)w(r)dr☑ is as Fig 5.35 on page 276. UESTC-Digital transmission through the AWGN channel Prof李晓峰 10
