摘要
基于最大似然思想,研究一种新的基于多符号检测(Multi-Symbol Detection,MSD)的PCM/FM遥测信号软解调方法。详细介绍此种解调方法的基本原理及实现过程,分析影响解调的同步因素并制定相应的同步策略。通过实测数据的测试表明,该方法解调性能优越,具有一定的应用价值。
Based on maximum likelihood, a new soft demodulation method of PCM/FM telemetry signals based on symbol detection （ multi - symbol detection, MSD ） is researched. The basic principle of the demodulation method and the implementation process are introduced, the demodulation and synchronization factors are analyzed and the corresponding synchronization strategies are formulated. The test result of measured data shows that the proposed method demodulation performance is superior, which has certain ap- plication value.
