摘要 针对CDMA系统抗干扰和抗截获的特点,首先对扩频码的性能指标及影响进行了分析,然后对线性和非线性序列进行了讨论,提出了扩频码的优选准则,综合考虑扩频码的相关性能、平衡特性和线性复杂度以及前向信道和反向信道的不同特点进行扩频码的优选,得到了数目较多、性能较好的扩频序列集合。 Considering CDMA's anti-jamming and high-security characteristics,firstly,the analysis of performance and influence of PN codes are given,then this paper deeply discusses linear and nonlinear sequences,reach es the rule for selecting PN codes.Joint ing balance property,stochastic property and linear complexity,authors choice appropriate PN codes for forward and reverse access channel respectively,get numerous good codes.
