特定码 meaning in Chinese

special code

The algebraic decoding algorithms are researched , and such as the common algorithm for the codes whose error correction ability is low , and the iterative algorithm for those whose error correction ability is great . programs are implemented for ( 27 , 9 ) rs and ( 54 , 18 ) rs
首先本文讨论了rs码的代数译码算法，包括纠错能力比较小的一般译码算法和适用于纠错能力强的迭代译码算法，并针对两种特定码字rs ( 27 ， 9 )和rs ( 54 ， 18 )进行了具体编程实现。
