pseudo channel 中文意思是什麼
pseudo channel
解釋
虛擬通道-
It takes use of pseudo - random technology, dynamic adaptive technology, multi - channel technology, random position embed technology and so no. so the digital watermarking can resist the physical process of printing and scanning. at the same time, the watermark is binary image which includes a great deal of information, such as personal id, secret information, even a piece of map
本文特別針對印刷和掃描給數字圖像帶來的誤差的問題，設計了一種新的水印演算法，綜合運用了偽隨機處理技術、動態自適應技術、不同應用選擇不用頻帶處理技術、隨機位置嵌入技術、多通道嵌入等技術，使得本文所設計的水印演算法能夠抵抗印刷和掃描的物理轉換過程，同時本文所設計的水印是二值圖像，能夠承載大量的信息，例如個人id 、機密信息、商標標識，甚至可以是一幅地圖。 -
( 3 ) a blind channel estimator based on the aid of pseudo - pilot - symbols ( pps ) is proposed in term of the two characters of ofdm system : the finite alphabet property of information symbols and independent property between subchannels
（ 3 ）利用ofdm系統傳輸的信息符號為有限字符集和各子載波的相互獨立特性，提出了用偽導頻符號（ pps ）進行通道的盲估計演算法。 -
This thesis presents the acquisition method of synchronization codes and time mark codes under - 20db gaussian channel. then the total step length between initial state and current state can be calculated. basing on the step length, we can deduce the current state of pseudo - random codes, and implement the acquisition of the special pseudo - random codes
本文設計出時間標記碼在信噪比達- 20dd時的捕獲方案，在此基礎上提出了由偽碼歷經的狀態數，計運算元碼當前狀態的方法，從而獲得了在30秒內完成導航定位衛星信號直接捕獲的方法與實現方案。 -
And for those that want to use a pseudo - synchronous style over an asynchronous channel, please, please, please, see bobby woolf s book on designing messaging systems
