The signal with QMBOC modulation is a new generation of satellite navigation signal independently designed by China in accordance with international design constraints, and it is also the main enhancement object of BDSBAS. The model principle of the QMBOC is analyzed, and the signal characteristics are simulated and studied from the dimensions of time domain, frequency domain, and correlation domain, etc. The advantages and disadvantages of different receiving and processing strategies are compared and analyzed. The implementation of the full-matching receiving algorithm in the broadband mode is proposed, and kinds of verifications are carried out. The results show that the method referred has higher receiving gain and measurement accuracy, and can provide a reference for the solution of monitoring and measure receivers in high-end application scenarios.
