- 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
第二章从mtf的物理意义出发，首先研究了irfpamtf的测试原理，具体分析了irfpamtf的主要测试方法，讨论了适用于本项目的刀口测试法；其次，从目标衍射和串音干扰两个方面分析了测试系统的衍射现象；最后讨论了减小统计误差的mtf计算方法。 - 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
在现代通信的数据传输过程中，传输速率本质上是由传输的编码方式和调制方式决定的，因为编码方式和调制方式直接决定了线路频带利用率和码元抗干扰能力的好坏，因而直接决定了传输速率；但是在实际应用过程中，数据传输速率是不可能达到理想状况的，因为环境干扰、串音干扰等因素的存在使得线路的频带不可能被完全利用起来；因此，必须认真分析线路的噪声信号的特性以及噪声线路的模型，以便在编码方式和调制方式中针对性的做一些改进措施以改善调制波形的抗干扰能力，使得传输速率能够进一步提高。 - 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
近几年来， adsl在世界范围内得到充分的使用，广泛应用于视频点播、远程医疗、网上购物等各个方面。但是由于电话线网络是专门为传输低频信号而设计，而adsl的频谱范围在0 1 . 104mhz内，因此在传输adsl信号时，面临着信号衰减、线路噪声、串音干扰、桥接抽头反射和射频干扰等等多方面的问题，这就要求在adsl开通之前对线路进行一系列的测试。 - 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线路实际工作环境存在各种干扰，尤其当多用户时，串音干扰很严重，对于采用基于信道估计的时域均衡算法，如果使用对噪声敏感的算法进行信道估计，必然影响均衡效果，因此需要采用具有抗噪声，估计精度高
