摘要
针对水文遥测图像编码在ＶＨＦ／ＵＨＦ信道上传输的混合差错控制问题，并根据水文遥测站的具体情况，讨论和分析了卷积码的编译原理、软件实现方法及交错技术。构造了（２，１，７）扩散卷积码，对译码过程提出了一种改进的查表法，这种查表法所占用的内存单元较少，便于在８位单片机上实现。
The paper designed(2,1,7) convolution code in order to meet the demand of correcting the image transmission mixing errors in telemetry system,and presents a new decode method by tabling.This method has practical and easily accomplished on 8bit compute.The paper also discussed the encoding and decoding principle and the software relization and the crisscross technology of the convolutional code.
