telemetry carrier

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.

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。

Effect of co-channel interference on a carrier tracking loop and telemetry subsystem

同信道干扰对载波环和遥测分系统的影响

The effect of interference on a Carrier-to-Tracking Loop ( CTL) is analysed, and the critical value is determined under the tracking condition of CTL. The analysis of the effect of interference on a telemetry demodulation subsystem is emphasized.

分析了干扰对载波跟踪环路的影响，确定了载波环保持锁定的临界条件，重点分析了干扰对遥测解调分系统的影响。
