摘　　要：针对传统航天测控通信系统在测距精度、数据传输速率和抗干扰等方面的不足 ,将多载波码分多路存取 (MC CDMA)应用于航天测控通信系统。该方法不仅可以使测距精度达到数米 ,数据传输速率达到几十兆字节每秒 ,而且还具有抗干扰能力强。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.

关 键 词：航天测控通信系统 多载波CDMA技术 数据传输速率 抗干扰能力 数据传输速率
