linear compound meaning in Chinese

线型化合物
直链化合物

This thesis sets out from the two generation methods of non - linear long periodic sequence , analyzes the correlation of the pieces of long periodic non - linear compound codes by confidence interval estimation and massey algorithm . based on the analysis results , this thesis summarizes two basic rules - the linear complexity of the compound codes and the correlation of the pieces of long period codes are both improved with the increase of the length of partial m sequence . and then , the general methods of the generation of long periodic non - linear codes with special characters are presented
本文由两种非线性长序列的构造方法出发，利用区间估计的方法和梅西算法，分析长周期非线性序列的局部互相关特性和线性复杂度，再以多个序列的性能分析结果为指导，总结出序列的局部互相关特性随子序列m序列的截段长度的增加而改善和序列的线性复杂度随子序列m序列的截段长度的增加而增加这两条基本规律，进而提出构造满足人们不同要求的非线性长周期序列的一般思路。
