BOC Signal Acquisition Algorithm Based on Similar Enfoldment
International Journal of Aerospace Engineering, 2020 A BOC signal has been widely used in the Global Navigation Satellite System (GNSS). Although the BOC signal has many advantages, the autocorrelation function (ACF) of the BOC signal has lots of peaks, which makes signal acquisition difficult.
