An Improved Cross-Correlation Reconstruction Algorithm for BOC (2n, n)

With the development of new navigation signals, BOC modulation signals are applied gradually, however, BOC signals have brought new challenges in the synchronization acquisition. Considering the drawbacks of existing methods in side peaks suppression, researching the characters of BOC (2n, n) and putting forward CCFR(Cross-correlation Function Reconstruction) base on the connection of multi-channel correlation function. By researching the theory and having a simulation, CCRF can eliminate the first side peak and suppress other side peaks. In addition, the performance of side peaks suppression is better than existing algorithms.
