串音干擾 的英文怎麼說
中文拼音 [chuànyīngānrǎo]
串音干擾
英文
crosstalk disturbance-
Transmition velocity relys on the style of encode and modulation essentially during modern data transmition for the quality of using line bandwidth and the immunity of code ties on them tightly. but it is important that the velocity of data transmition reaches its limitation in fact for the interface of environment and cross - talk. so for the improvement of transmition velocity, we must analyze the characteristics of noise signal and the model of line deeply and then take some useful measures to better the immunity of modulation wave
在現代通信的數據傳輸過程中，傳輸速率本質上是由傳輸的編碼方式和調制方式決定的，因為編碼方式和調制方式直接決定了線路頻帶利用率和碼元抗干擾能力的好壞，因而直接決定了傳輸速率；但是在實際應用過程中，數據傳輸速率是不可能達到理想狀況的，因為環境干擾、串音干擾等因素的存在使得線路的頻帶不可能被完全利用起來；因此，必須認真分析線路的噪聲信號的特性以及噪聲線路的模型，以便在編碼方式和調制方式中針對性的做一些改進措施以改善調制波形的抗干擾能力，使得傳輸速率能夠進一步提高。For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近幾年來， adsl在世界范圍內得到充分的使用，廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計，而adsl的頻譜范圍在0 1 . 104mhz內，因此在傳輸adsl信號時，面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題，這就要求在adsl開通之前對線路進行一系列的測試。In this case, time domain equalization algorithm based on channel estimation will influence equalization effect if choosing noise sensitive algorithm to estimate channel, so it is necessary to adopt an anti - noise and high estimation precision estimation algorithm. in this dissertation, a new time domain equalization algorithm based on low rank hankel approximati
Dsl線路實際工作環境存在各種干擾，尤其當多用戶時，串音干擾很嚴重，對于採用基於通道估計的時域均衡演算法，如果使用對噪聲敏感的演算法進行通道估計，必然影響均衡效果，因此需要採用具有抗噪聲，估計精度高In chapter 2, firstly the physics concept of mtf and the measurement principle of irfpa mtf are shown, the main measurement methods are described in detail ; secondly the diffraction of the measurement system is analyzed from two aspects : target diffraction and crosstalk interfere ; finally the algorithm method for eliminating statistical errors of mtf is discussed
第二章從mtf的物理意義出發，首先研究了irfpamtf的測試原理，具體分析了irfpamtf的主要測試方法，討論了適用於本項目的刀口測試法；其次，從目標衍射和串音干擾兩個方面分析了測試系統的衍射現象；最後討論了減小統計誤差的mtf計算方法。Use fiber for any connection to a switch or server, and for any gigabit connection that requires a cable run exceeding 100 meters or that flows through an area in which radio interference, crosstalk, or attenuation might be a problem
對于任何一個交換機或服務器的連接，或超過100米的任何千兆連接，都要使用光纜，如果一個連接可能通過有無線電干擾、串音、衰減等問題的區域，該連接也要使用光纜。分享友人
