AltBOC An apparatus and method for unambiguous AltBOCAlternative Binary Offset Carrier signal tracking considering combination operator features

摘要

In the present invention, the receiving unit for receiving the AltBOC signal, the received AltBOC signal is classified into a plurality of subcarriers having different components, and the divided parts of the plurality of subcarriers are divided into N (N is a natural number) pulses, A partial subcarrier generator for generating a plurality of partial subcarriers for each of the plurality of subcarriers, a partial correlation function obtaining unit for obtaining a plurality of partial correlation functions through correlation with a plurality of partial subcarriers and a received signal, and the same time zone or time difference (time AltBOC signal tracking device considering the characteristics of a coupling operator having a partial subcarrier coupling unit that combines a plurality of partial correlation functions with difference of zero to generate N total partial correlation functions and combines the generated total partial correlation function with a coupling operator Provides
