| 摘 要： | 在分析数传信道差错特性的基础上，结合测控系统实际数传信道特点，将测控系统的数传信道定位成有记忆、生成型、更新型的信道模型。最后选用了双状态马尔科夫链模型作为信道干扰仿真的数学模型，并采用误码率调节方法实现干扰仿真的灵活控制。

| Abstract: | Data transmission channel of TT＆C system is determined as a memorized, generated and updated model based on analysis of its error characteristics and actual characteristics of data transmission channel in this paper. Finally,the Markov stochastic model is selected as the mathematical model of the noise channel simulation. Then the flexible control of noise channel is realised by use of bit error rate variant. |
