| Popis: |
The accuracy transmission of a binary offset carrier (BOC) signal is always affected by narrowband interference (NBI), and a novel anti-jamming acquisition algorithm based on all-phase processing finite impulse response (apFIR) and partially matched filter-all phase fast Fourier transform (PMF-apFFT) is proposed in this paper. First, an apFIR filter with precise settings for arbitrary notch points was constructed, and then the PMF-apFFT method was adopted to achieve the acquisition of the contaminated BOC signals. Simulation and analysis show that the proposed algorithm can effectively suppress NBI and simultaneously complete correct pseudo-random (PN) phase search and accurate Doppler frequency estimation, and it shows superior performance in mean square error (MSE) and detection probability. |
