restored signal 中文意思是什麼
restored signal
解釋
恢復的信號-
Only when olt receives the first few bits of the uplink burst of onu and achieves the bit synchronization can the onu signal be restored
Olt必須在收到onu上行突發的前幾個比特內實現比特同步,才能恢復onu的信號。 -
The results indicate that the soliton amplitude slightly decreases in the border between the single - mode fiber ( smf ) and the dispersion compensation fiber ( dcf ), but and its shape remains unchanged, while its signal amplitude is amplified when it passes an amplifier and its shape automatically restored
研究表明,在普通光纖與色散補償光纖的交界處,孤波的幅度有所降低,但其形狀保持不變;光孤子通過放大器后其幅度得到放大,其形狀將自動得到恢復。 -
Some valuable conclusions are summarized by theoretical analysis and simulation experiments : from the side of signal processing, pulse jamming can be deleted by the method of time - domain sliding window accumulation and can be restored by interpolative prediction. ; gauss white nose can be attenuated while jamming disperse point - target by the method of time - frequency analysis in time - frequency domain. ; radio frequency noise jamming can be deleted by the method of average range frequency spectrum and notching in frequency domain
通過大量的理論分析和模擬實驗,得到了一批具有一定價值的結論:從信號處理的角度出發,對于脈沖式干擾,能夠運用時域滑動窗口積累的方法去掉,並且通過預測插值得到較好的恢復;對于高斯白噪聲干擾,在時頻變換域內應用時頻分析方法可減小其對分散點目標的干擾;對于射頻噪聲,通過平均距離頻頻法和頻域陷波的方法可以去掉;從改變合成孔徑雷達系統角度出發,類似雙基地雷達能夠避免各種干擾,對發射信號進行調幅,調相以及改變調頻斜率都是較好的抗干擾方法。
