循环码关于软判决译码的一条性质

A Property of Some Cyclic Codes about its Soft-Decision Decoding

研究了循环码的性质，给出并证明了关于编码率ｋ／ｎ＜（ｔ＋１）／（ｄ—１）的循环码的一条定理，该定理有利于降低软判决译码复杂度．

The property of cyclic codes is studied in this paper, and a theorem is presented and proved, which can be employed to reduce the complexity of its soft-decision decoding.
