Abstract
Frequency hopping binary offset carrier (FH-BOC) signals use a wider band than other BOC signals, resulting in high signal tracking accuracy and low ambiguity for their correlation functions. Even with these improved metrics, ambiguities remain in correlation functions and could lead to false locking during code tracking. The FH-BOC signal is obtained from a time division multiple combining multiple BOC signals with different frequencies through a process called frequency hopping. This report outlines the common pulse component between several sub-carriers of the FH-BOC signal. This pulse is correlated with the received signal and combined to design an unambiguous correlation function for the FH-BOC signal. Compared to the FH-BOC signal’s correlation function, the designed unambiguous correlation function is less affected by multipaths because more power is concentrated at the main peak.
