摘要
国内外遥测工作频段涵盖L/S/C/X/Ka频段,主要测控工作体制为AM-FM、PCM-FM、PCM-PM、PCM-PSK-PM、PCM-BPSK-PM、PCM-QPSK-PM、PCM-CDMA-BPSK等.针对7种主要测控体制信号,梳理出6个反映信号特征的识别参数,设计了调制体制识别流程,仿真表明在SNR＞5 dB的条件下,针对7种体制的调制类型识别率可达到90%.
Abstract
The domestic and foreign telemetry frequency band covers L/S/C/X/Ka frequency band.The main telemetry and control systems are AM-FM,PCM-FM,PCM-PM,PCM-PSK-PM,PCM-BPSK-PM,PCM-QPSK-PM,PCM-CDMA-BPSK and so on.According to the 7 main signals,6 identification parameters reflecting the signal characteristics are carded out,and the identification process of modulation system is designed.The simulation results show that under the condition of SNR＞5 dB,the recognition rate of modulation types for the 7 systems can reach 90%.
