Examples
- The modeling and simulation of 3th generation ( 3g ) mobile communications satellite / terrestrial channels with every measurement environment is described
摘要描述了各种测试环境下的第三代移动通信地面卫星信道的建模及仿真实现。 - This project is oriented for the implementation of the receiving end of dvb - t channel , and pda receiving card based wince ( windows ce ) os . the end is engaged for receiving the downriver broadcasting data from the terrestrial channel . the project is based on the in - deep study of the dvb - t standard and the dvb data broadcasting specification
采用数字地面电视dvb - t / cofdm技术，设计制作信道接收机，本文称其为pda的接收板，并设计基于pda操作系统wince （ windowsce ）驱动程序，通过定制操作系统的方式载入pda ，实现数字视频的移动接收。 - We agree that hdtv and mobile reception should not be made mandatory for all multiplex operators . however , for the multiplex operators carrying the four existing terrestrial channels , adequate provision must be made to enable existing terrestrial broadcasters to offer hdtv andor other forms of enhanced tv services ( of which mobile reception is one of them ) in their digital broadcast
我们同意不应强制所有数码电视频道平台营办商执行高清晰度电视及流动接收服务，但是假若数码电视频道平台营办商播出现时四条地面频道时，政府应给与足够条款令现时地面广播机构有适当频谱提供高清晰度电视及或其他多功能电视服务(包括流动接收) 。 - The paper discusses the part of asic design of tcm ( trellis coded modulation ) in hdtv 8vsb terrestrial channel broadcasting receiver chip . in testing , the tcm can improve the signal - to - noise by 3 . 3db compared with uncoded 4 - vsb modulation , and with the 12 path intrasegment interleaving in tcm coding and viterbi decoding , system can control short burst noise error efficiently
在高清晰度电视信道接收芯片中内码是8 ? vsb的格状编码，在系统性能上使用tcm编码要比未编码有3 . 3db的编码增益，另外在格状编码中加入了12路的内交织，可有效的抑制短的突发噪声对接收端viterbi解码性能的影响。
