Sentence examples for matched filter given from inspiring English sources

From the output of the matched filter given in (5), the desired signal is given by (sum _{n=1}^{N}A^{1}b_{n}^{l,1}h_{mn}^{l}), where the channel taps α i are no longer individual Rayleigh fading contributions but are rather a sum of all Rayleigh fading contributions.

We compare (in Figure 5) the distributions of (s tau)) corresponding to the uniform filter ((f(t) = 1)) and a matched filter (a filter function proportional to the measurement record, see [37, 38]), shown in Figure 4. Figure 4 The approximate matched filter given by Eq. ( 58 ), for use in obtaining a measurement signal (pmb{s tau)}) given a photocurrent time trace (pmb{j t)}).

The probability of detection, Pd,1, and false alarm, Pf,1, of a matched filter are given [23] as P d, 1 = Q λ 1 − E σ w E. (4) P f, 1 = Q λ 1 σ w E. (5).
