Finally, simulations are conducted, the results show that the revised PMF-FFT methods can successfully acquire B1I ... WebThe incoherent integration reduces the variance of the noise and better defines the power spectra, but it does not change the mean values of signal (P) and noise spectral (P N) …
WebBased on these characteristics, an incoherent integration detection method is proposed, which makes full use of the energy of multipath signals. At the same time, the detection … WebMay 7, 2024 · The coherent integration time and incoherence times are first affected by the sensitivity threshold (−152 dBm), as shown in Fig. 8. The detection probability is set as P_ {D} = 90\%, the false alarm probability of a single search unit is 1e−8, the longer the coherent integration time, the higher the detection probability (acquisition sensitivity).
