This paper discribes the effect of co-channel interference on the ground TT&C station between satellite-ground links.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. The interference has an effect on the Bit-Error-Rate (BER) by two ways. On the one hand, the reference phase jitter caused by a carrier recovery loop will have an indirect effect on BER. On the other hand, the interference introduced directly into a coherent detection device will directiy give raise to increase BER.The results of the effects can be expressed in terms of the loss of input Signal-to-Noise ratio E_b/N_0 at the same BER.

文中讨论了星地链路中同信道干扰对地面TT&C站的影响;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。干扰通过两个途径影响误码率:一是通过载波恢复环路,造成参考相位抖动,间接影响误码率;二是直接进入相干检测设备,直接影响误码率。这些影响的结果可用同等误码率下输入信噪比E_b/N_0的损耗表示。

There are a lot of digital signal code patterns can be used in telemetry systems.In telemetry demodulation system,the NRZL code is usually used as the output code pattern ,so it is necessary to convert the other code patterns to NRZL code.In this paper,some converting circuits based on matching filtering, threshold decision,sample,shift and XOR are introduced,which have been used in telemetry system education.

在遥测系统中有许多种数字信号码型可以使用。在遥测解调分系统中 ,通常采用 NRZL 码作为输出码型 ,这就需要将系统输入的其它码型反变换为 NRZL 码。文中介绍一种在实验教学遥测系统中采用的利用匹配滤波、门限判决、采样、移位、异或的手段来实现码型反变换的方法。

A new miniaturized multiplex FM/FM telemetry demodulation system is introduced.It is a specialty in this system that a programmable universal active filter,MAX260/1/2,was used.This makes center frequency and bandwidth of bandpass filter realized only by programming,and any resistances or capacitances weren't needed.This system has good flexibility and can be miniaturized easily.It can be used for IRIG PBW Channel 1 to Channel 18.The realization of this system was precisely introduced.

介绍一种可小型化的 FM/ FM多路遥测信号副载波解调器 ,该解调器使用一种可编程的通用有源滤波器 MAX2 6 0 / 2 6 1/ 2 6 2芯片 ,使得分路滤波器的中心频率及通带大小只需通过编程即可实现 ,不需要任何阻容器件 ,因此系统不仅具有很好的灵活性 ,而且易于实现小型化。对通道中心频率较低的 IRIG- PBW体制 1到 18通道均可适用。详细介绍实现方法
