Abstract
The establishment of the Global Navigation Satellite System can provide users with precise navigation information, including speed, three-dimensional position and precise time. In this paper, the signal structure of Beidou B1I is introduced firstly. Then, based on the known rough carrier Doppler frequency shift and pseudo-code phase, this paper analyzes the different forms of carrier loops, including FLL, PLL and FLL+PLL carrier loops. The advantages and disadvantages of their performance are compared. Finally, the simulation and data demodulation results are given.
