Method and Device for TMBOC(Time-Multiplexed Binary Offset Carrier) signal tracking based on selected pulses

摘要

TMBOC signal non-ambiguity tracking method of the present invention comprises the steps of receiving a TMBOC signal; Generating a first local signal from the received TMBOC signal; Discriminating a high frequency subcarrier pulse component and a low frequency subcarrier pulse component from the generated first local signal, and generating a second local signal and a third local signal based on the high frequency subcarrier pulse component and the low frequency subcarrier pulse component; Reinterpreting each of the second local signal and the third local signal as a sum of a plurality of square wave pulses, and regrouping pulses present at the same position among the plurality of square wave pulses; Correlating the regrouped pulse group with the TMBOC signal; And generating an unambiguous correlation function based on a correlation result between the regrouped pulse group and the TMBOC signal.
