Abstract

Abstract: MBOC modulation signal is adopted by Galileo and GPS system for interoperation. Based on studying the generating principle of MBOC(time division data modulation binary offset carrier)modulation signal, the characteristics of MBOC modulation signal are analyzed. The MBOC modulation based on Field-Programmable Gate Array (FPGA) is realized by Verilog. The result is provided by simulation and test, and it shows that the implementation scheme is feasible. It is of great significance for the research of the new structure of navigation signal and the development of new generation receiver.
