【摘要】 从空间遥感数字图像信息的存储载体——半导体固态图像存储器出发，讨论了空间应用时存储器的数据错误类型及其对策。针对半导体存储器的各种组织形式，给出了选择纠错码的原则，还分析了不同的纠错码的纠错性能。并且重点论述了适合于空间应用中的存储器纠错码——ＲＳ纠错码：较详细地给出了ＲＳ码的结构、性质及其编、译码的基本过程和ＲＳ码译码算法的最新进展情况，并且介绍了与ＲＳ码结合紧密的数据交织技术及解交织技术。讨论了ＲＳ纠错码在目前空间应用固态图像存储器中纠突发性错误和随机性错误时的特殊能力。更多还原

【Abstract】 Based on the remote sensing digital image information carrier semiconductor solid state image data recorder, the data error types and their countermeasure were analyzed. According to the organization of semiconductor recorder, the principle of selecting the error correcting codes was presented and the performance of the error correcting codes was analyzed. Because of its special ability in correcting the burst error and random error of semiconductor solid state image data recorder, the RS error correcting codes’ organization and performance were discussed in detail. Further more, the procedure of RS codes’ encoding and decoding were also under ours discussion. The progresses of RS code’s decoding algorithm are also discussed. In the end, we present the technology of data interleaving.更多还原
