Abstract
As quickly growing of global navigation satellite system community, there is increasing interest in new signals for military and civilian uses. New signals must provide more robustness, higher performance, and greater capacity than already-existing signals and compliant with the radio frequency compatibility rule with existing and planned signals. This paper presents a class of particularly attractive modulations called Generalized Binary Offset Carrier (GBOC) modulations, and demonstrates their essential characteristics and performance in the signal design of BeiDou system. The GBOC modulations can offer additional degrees of freedom for shaping the signal’s spectrum and provide superior performance in code tracking, multipath and compatibility than other BPSK and BOC modulations. The results show that the proposed modulation can provide potential opportunities for BeiDou satellite navigation system modernization and construction.
