摘要
本文以最新组合编码方法为依据,在复数旋转码的基础上,提出了一种可以表示为[2p_i^2-2pi+2,p_i^2-p_i+1,p_i+1]的线性组合码(其中 p_i+1为最小码距,p_i≥2)。它具有原理简单,编码译码速度较快,编码译码过程相似,能纠多位错等特点。在有些情况下可以利用复数旋转码的编译方法,如果稍加变换还可以作为一种纠错——保密两用码。
This paper gives a Cross Associated Code which can be pre- sented as[2p_i^2-2p_i+2,p_i^2-p_i+1,p_i+1] (which p_i+1 is minimum code range,p_i≥2) according to the latest method of composite encoding and on the basis of the complex-rotary code.It has many specialities such as simple theory,faster speed and rese- mble process of decoding and encoding and can correct many bits,errors.In some cases the way of compilation of complex- rotary code can be used as a double code of correcting and kee- ping secret with some exchangs.
