【Abstract】 On the basis of shortcoming of traditional spaceflight telemetry, tracking and command systems in measure accuracy, data speed and resist interfere, multi carrier code division multiple access (MC CDMA) technology is applied to spaceflight in this paper. The technique not only can make the accuracy to meters and the data speed to tens Mb/s, but also has the advantages of anti jamming, multi object trace and simplicity.更多还原
