摘　　要：针对实际扩频通信系统对序列进行截短使用的需要,采用直接序列截短法对所获得的平衡Gold序列进行截短,通过MATLAB平台仿真,分析序列截短前后各方面特性的变化及影响程度.研究表明,序列截短后的平衡性及相关性等性能有所降低,但相比截短前的序列性能仍非常接近.为了保证序列截短后的性能满足实际系统的需求,应选择合适的截短方法和截短长度.For the needs of actual Spreading spectrum communication system to using the truncated sequence, this paper using the method of direct sequence truncated to the obtained balance a truncated Gold sequences. Ana- lyzing the characteristics change and influence degree of the sequence before and after truncating based on the MATLAB as the simulation platform to obtain the data and conclusions. The study shows that the balance and corre- lation of after the sequence truncated decreases, but performance is still very close with the sequence before trunca- ting. In order to ensure that after the truncated sequence performance meets the needs of actual system, should choose the appropriate methods and shortened length.
