【Abstract】 Study On Joint Location Technology Based On TDOA/FDOALi Sheng Zhang Yang(College of Electronic Engineering, UESTC of China Chengdu 610054)Abstract In this paper, the CAF-SOS algorithm based on Second-order cumulant use to estimate TDOA and FDOA has been discussed in the location system of two satellites. To reduce influence of the correlation between two additive noise sources, the CAF-HOS based on High-order cumulant also has been discussed. Utilized CAF-SOS and CAF-HOS, TDOA and FDOA can be simultaneously estimated through computer simulation.更多还原
