Abstract

The invention provides an unambiguous acquisition method and device for BOC (n, n) signals and comprises the steps: - acquire the digital intermediate frequency signal; - mix the signal With the local carrier wave to get a carrier cancellation signal; - put the carrier cancellation signal in a low-pass filter and put the signal sample into a partial matched filter, wherein the local code and the carrier cancellation signal are divided into several segments, and the two segments are multiplied accordingly to get several points, - put the accumulated value of the points cached under FFT to obtain the results to be calculated via the modulo operation to get the maximum value - compare to the threshold; - If smaller, indicate that the signal is not successfully acquired. At this time, move the code phase and repeat the steps above till the signal is captured.
