- 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。 - 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。 - some critical coding and modulation techniques in uav communication have been discussed in this thesis, including differential phase keying ( dpsk ), modulation multiple symbol detection ( msd ), adaptive trellis coded modulation ( atcm ), and space-time coding . this work was supported by the national defense 973 project . uav communication has many sophisticated technologies
