网格编码调制 meaning in English
tcm trellis coded modulation
Examples
- In chapter 4 , the coding and modulation for lmds system are discussed , which pays emphasis on the pragmatic tcm coding and modulation scheme
第四章对lmds系统中所要用到的调制解调技术进行了探讨。重点讨论了ptcm实用网格编码调制。 - Coded modulation technique is a hot issue in code field in recent 20 years . it appeared in 1982 when ungerboeck proposed tcm theory . and then it apply widely soon
编码调制是近二十年来编码界的一大热点,它的出现是以ungerboeck在1982年提出网格编码调制( tcm , trelliscodedmodulation )理论为标志。 - Since the fundamental idea of tcq originates from trellis coded modulation , in order to comprehend tcq , it firstly introduces tcm . also , because viterbi decoding algorithm is the key of coding gain of tcm and tcq , it particularly introduces convolutional coding and viterbi decoding algorithm
由于tcq的基本思想源于tcm ，较好地掌握tcm的思想有助于深刻理解tcq ，所以首先介绍了网格编码调制；维特比算法是tcm和tcq提高编码增益的关键，文中对tcm和tcq都要用到的卷积编码和维特比译码也作了详细的介绍。 - The technology of trellis coded modulation ( tcm ) and viterbi decoding which could achieve high transmitting rate at a low bit ' error rate are demonstrated in detail . and then the design and achievement of itu - t v . 32 modem that based on one - dimensional tcm are expatiated . the paper also discusses the multi - dimensional tcm the itu - t v . 34 modem that based on it and tcm ' s application in the carrier communication
文中深入研究了可保证一定误码率的情况下能实现较高传输速率的网格编码调制( tcm )技术和维特比译码技术，阐述了基于单维网格编码调制的itu - tv . 32modem的设计和实现，讨论了多维网格编码调制技术和基于其的itu - tv . 34modem ，并对网格编码调制在载波通信中的应用作了简单介绍。
