Unambiguous Algorithm Analysis for BOC Signal Based on PCF
Yishan Pan · Science Technology and Engineering · 2013
For the problem of unambiguity in synchronization which is caused by the autocorrelation function for BOC(Binary Offset Carrier) signals with multiple peaks,a synchronization algorithm based on PCF(Pseudo Correlation Function) is proposed. The local auxiliary signal is modulated with local PN code and local subcarrier,and then the result is correlated with received signal. It obtained a correlated function with single peak. Performance analysis and simulation comparison show that the proposed algorithm can be a solution to eliminate unambiguity completely. The acquisition accuracy and acquisition performance can be improved by modifying the value of parament.
