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 to W(1) Sampling r(0) h(0)= y() x(I) MF is the optimal filter ”(T-) Compute, T)= h)*r(r =he)r(-)dr =∫he)r(T-rdr =h(r)s(T-r)dr+[h(r)n(T-r)dr UESTC-Digital transmission through the AWGN channel Prof李晓峰 9
