Performance simulation of TPC code in PCM-FM telemetry system

利用Matlab搭建PCM-FM遥测系统和TPC编解码仿真模型,通过仿真验证在PCM-FM遥测系统中使用TPC码后对系统的误码率改善情况。由仿真结果可知,在TPC码码率为0.5时可获得5dB左右的增益,同时还对影响TPC增益的各个解码参数进行了详细仿真。

Using Matlab to build PCM-FM telemetry system and TPC code simulation model.The performance simulation of TPC code in PCM-FM telemetry system is introduced.The simulation result shows that the TPC code of code-rate is 0.5 can gain 5 dB.Parameters of TPC decoding are simulated in this paper.
