摘　　要：Turbo码的译码性能几乎接近shannon理论极限,实现Turbo译码器对于降低信道传输的误码率、提高传输可靠性具有重要的意义。借助Xilinx EDK软硬件开发工具构建了一个Turbo译码器和以太网络传输的SoPC系统,实现了网络通信下的Turbo译码,并将所构建SoPC系统的硬件比特流和软件程序下载到Xilinx公司的Spartan-3S1500开发板上验证成功。实验结果表明,所设计的SoPC系统能实现数据的动态传输和信道纠错。Decoding performance of Turbo codes almost approaches to the limit of Shannon theory.The implementation of Turbo decoder is important for reducing the error bits rate in channel transmission and improving transmission reliability.An SoPC system of Turbo decoder and Ethernet-transmission is constructed by using the tool of Xilinx EDK software and hardware development,which realises the Turbo decoding in network communication.The hardware bit stream and software program of the constructed SoPC system are downloaded to Spartan-3s1500 development board of Xilinx Inc.and their correctness are proved successfully.Experiments show that the designed SoPC system can realise dynamic data transmission and channel＇s error correction.
