Moreover , theory of the random pulse position modulation and random binary phase - coded ( rppm & rbpc ) pulse doppler is also discussed 在此基礎上,進一步討論了隨機脈位調制加隨機二相碼調相脈沖多普勒雷達原理。
By introducing oppm ( overlap pulse position modulation ) , the system ' s performances are improved also . 5 study wireless optical cdma system 通過引入oppm (重疊脈沖脈位調制)方式,進一步提高了系統(tǒng)的傳輸效率。
This system realize the chaos arithmetic directly by hardware and non - chaos synchronization communication by chaotic pulse position modulation technology 該系統(tǒng)直接用硬件實現(xiàn)混沌迭代算法,運用混沌脈沖位置調制技術實現(xiàn)無混沌同步通信。
