Performance Evaluation of Interoperable Signals on B2 Band

Interoperability has become an important trend among future global satellite navigation systems. As the interoperable signal options proposed on B2 band, this paper evaluated AltBOC, TD-AltBOC and ACED in aspects of ranging accuracy, sensibility, Time to First Fix (TTFF), anti-interference performance, anti-multipath performance, multiplexing efficiency, cross correlation property and complexity. It can be a reference for COMPASS signal design.
