Novel Code of ZCZ Based on m-Sequences
Zhicheng Jia · Microcomputer Information · 2010
Based on the knowledge of m-sequences, a binary generalized orthogonal sequences (GOS), called m-ZCZ code, is constructed. The value of ZCZ length breaks through the restriction, and can be flexibly chosen to match the practical channel in a high degree. Then a new method of extension to the m-ZCZ code set size which using more sub codes was defined. The new code breaks through the restriction of ZCZ to the size of code, greatly expanded the size of the code. The m-ZCZ sequence set can be applied to the quasi-synchronous CDMA system and reduce even eliminate co-channel interference, so increase the system capability.
