Our results show that pmd induces pulse broadening randomly in high bit - rate optical fiber communications ; the synchronous amplitude modulation control may correct directly any position change of timing jitter and soliton interaction, so the transmission distance and pulse quality will increase further
研究結果表明對于高速率傳輸系統， pmd對脈沖的影響在時域上表現為脈沖形狀的展寬，這種展寬是隨機的；而同步幅度調制是在時域上，將發生形變的脈沖通過振幅調制，恢復原形，從而提高脈沖的傳輸性能。 -
In the border router, we design a new diffserv scheduler ( bswcs : bit - based weight time slot compensate scheduler ), which dynamically adjust the weighted quantum of service. combined with the error concealment technology in the video decoder, in case of severe congestion which cause losing a lot of ip packets, these algorithms have been proved effective, hence the delay, jitter and the perceived picture quality all meet requirement for real - time video transmission
4建立了一個區分服務網路模型，根據視頻編碼的特點，提出了一種針對視幀傳輸的新的服務優先等級標識演算法，即根據不同視頻幀解碼時的重要程度和網路的傳輸狀況將不同視頻幀的數據包標記為不同等級，賦予不同的質量保證。 -
By theory and practice simulation, the several types of constant envelope modulation techniques are analyzed and compared, including theirs modulation principle, phase path, the modulated wave envelope, power spectrums, error bit rate and the influence of its power spectrums of the band - limited and non - linear, etc. especially we have researched the ijf - oqpsk modulation technique, and the performance of its inter - symbol interference and time jitter free, and its strongly resisting of spectral spreading
結合理論和實驗模擬結果，分析討論了衛星通信中的各種恆包絡調制技術，對它們的調制原理，相位路徑，已調波包絡，功率譜密度，誤碼性能，以及帶限非線性通道對其功率譜的影響等方面都作了研究和比較。特別研究了ijf ? oqpsk在消除碼間干擾和定時抖動方面的性能及其優良的旁瓣特性和抑制頻譜擴展特性。 -
The dynamic bit rate allocation module receives relevant data from the loss rate of multi - media data packet, jitter, delay, and compares these data with predefined values to make one of these 3 decisions that : decrease the video bit rate ( stat = decrease ), or maintain current video bit rate ( stat = hold ), or increase video bit rate ( stat = inccease ). the video bit rate will be adjusted according to the decision and the total bit rate is changed accordingly. in this way the impact of network environmental variation is settled, and consequently the adaptability of videoconference systems in remote education area is improved
整個模型從rtcp協議獲得多媒體數據包丟失率（ lossrate ） 、抖動（ jitter ） 、延時（ delay ）的相關數據，這些數據與預先設定好的閥值作比較，得出減小視頻位速率（ stat = dectease ） 、維持視頻位速率不變（ stat = hold ）或增大視頻位速率（ stat = increase ）的決定，模塊根據這些決定對視頻位速率進行相應的調整，從而總的位速率也相應變化，這樣可以減小由於網路環境變化而帶來的影響，從而提高視頻會議在遠程教育應用中的實用性。 -
The effects of sampling clock jitter on signal - to - noise ratio ( snr ) and effective bit ( enob ) performance discussed in section 3 are even more dramatic in undersampling applications because of the higher input signal frequencies
在第三章討論的采樣時鐘抖動對信噪比和有效位性能的影響在欠采樣應用中因為更高的輸入信號頻率顯得更有戲劇性。
