| 摘 要： | 针对再入遥测环境下遥测信号信噪比较低,而传统解调方法解调门限较高的问题,结合PCM/FM信号相位特性,研究一种基于多符号检测(MSD)的软件化解调方法;对连续观测到的若干个码元信号与本地信号进行联合检测。研究相应的同步算法保障解调的顺利进行。仿真和测试结果验证了MSD的有效性。

| Abstract: | For reentry telemetry environment remote signal low signal noise ratio (SNR), and traditional demodulation method demodulation higher threshold, combined with PCM/FM signal phase characteristic, based on a symbol detection (MSD) software dissolve adjustment methods: continuous observed several element signal and local signal joint detection. And the corresponding synchronous demodulation algorithm ensure smoothly. Simulation and test results verified the effectiveness of the MSD. |
