The High Efficiency Method of Tracking Base on Navigation Signal

With the development of navigation signal in direct spread spectrum communication, in order to accurately receive the signal, it¿s important for processing pseudo code phase in the receiver. Simultaneity, precision demodulation is required to do in the synchronization process in receiver. nevertheless, as the appearance of new signal with new characteristics, the new challenges are issued in more precise synchronization, higher efficiency and less complexity. It is also the most difficulty in the research. As a result, based on existing track methods, in allusion to the characteristics of long-periods/non- periods, the improved wave tracking algorithm is proposed with higher efficiency and faster processing speed. It is also simulated in MATLAB, and the result of simulation is analyzed. The result was proved: the algorithm is more efficient.
