Sdd苏丹第纳尔 - Very large data bases , santiago de chile , chile , september 1994 , pp . 85 - 95 . 19 bernstein p a , goodman n et al . query processing in a system for distributed database sdd - 1
接着介绍了包括语义浏览器可视化语义映射与注册以及查询重写与分配等一组支持数据库集成和语义信息检索的工具。 - As for traditional sdd - 1 algorithm , this paper tries to improve it in the following aspects : ( 1 ) during data transportation , this paper adopts data compression technology . another encoding model - tag model - is put forward here which is different from existing models
本文试图从以下方面对这类算法进行改进： ( 1 )在数据传输过程中，引进数据压缩技术，提出不同于现有的压缩编码模式-标记模式，并给出tag算法的实现。 - So the new algorithm can be applied . based on the new algorithm mentioned above , two methods of soft decision decoding on rs - complex rotary codes , sdd i and sdd ii , are proposed according to the character of encoding and decoding of the codes
通过计算机模拟仿真，发现sdd软判决译码算法和sdd软判决译码算法的复杂度都不大于gf ( 2 ~ m )上多元码字的软判决译码算法，尤其是sdd算法的复杂度总体上还小于多元码字的软判决译码算法。 - A new algorithm of soft decision decoding for the codes over gf ( 2m ) is proposed on the basis of word - by - word decoding algorithm . the new algorithm improves the decoding performance by 2 ~ 3db , and the number of tries sequences is far less than the number of tries sequences of the existing algorithm over gf ( 2m )
根据构造的rs -复转码的编译码特点，结合本论文所提出的gf ( 2 ~ m )上多元码字的软判决译码算法，讨论并设计实现了rs -复转码的两种软判决译码算法，即sdd软判决译码算法和sdd软判决译码算法。
