multi-pulse jamming 中文意思是什麼
multi-pulse jamming
解釋
多脈沖干擾-
Then we introduce pulse position modulation ( ppm ) using pn code and analysis its multi - access performance, system capacity and power spectrum density. on the basis of those analyses, we study the pulse shape and the anti - jamming ability of the system. at last, multiple access with pseudochaotic time hopping is introduce
本文首先闡述了uwb脈沖通信系統的基本原理，重點介紹了用偽隨機碼跳時的ppm （脈沖位置調制）調制，分析了他的多址性能、系統容量和功率譜密度，在此基礎上研究了改進性能的發射信號形狀和系統抗干擾能力，最後介紹了偽混沌碼跳時的多址方式。 -
The system has a good security and can prevent the pervasion of mistake code, has a well anti - jamming ability and so on. some substantial and groping work has been done in the process of using chaos security communication in pulse wireless system and the multi - access communication of chaotic pulse position modulation
系統具有很高的保密性，具有防誤碼擴散，抗干擾能力強等特點，同時也為混沌保密通信應用於脈沖無線電系統以及混沌脈沖位置調制的多址通信方面做了一些實質性和探索性的工作。
