During the designing of data transmission system , we should assure the dependability of transmission , descend the transmittal power and decrease the volume . therefore , using error control technology in base - band processing unit is consumedly important 数据传输系统的设计,要保证传输的可靠性,降低通信设备的发射功率,减小体积,因此在基带处理单元中进行差错控制设计具有非常重要的意义。
We first retrospect the development history of relevant fields , and introduce the construction and rudiment of the base - band processing unit . after analyzing convolutional code principle and viterbi algorithm , we determine to use ( 2 , 1 , 9 ) convolutional code in this designing , and give general introduction of develop platform and designing language . then we explore the concrete realization of base - band processing unit , and bring up overall designing scheme 文中回顾了相关领域的发展历史,给出基带处理单元的组成及其基本原理,对卷积码原理和viterbi算法进行了分析,确定了用于本设计的纠错码类型( 2 , 1 , 9 )卷积码,同时对开发平台及设计语言进行了简要介绍。
We mainly explore the realization scheme of base - band processing unit of data transmission system using fpga in this paper . with the research of the base - band processing unit and designing method of fpga , we detailedly explore convolutional coding and viterbi decoding , and accomplish the designing of base - band processing unit in fpga develop platform of altera company 论文对基带处理单元和fpga设计方法进行了相关研究,尤其对基带处理单元中卷积码编码和viterbi译码进行了深入的研究,并应用altera公司最新的fpga开发平台quartusii5 . 1完成了基带处理单元的设计。
