摘　　要：直扩系统因其良好的抗干扰性能在通信上获得了广泛应用,其所用扩频码具有连续功率谱或离散功率谱。以处理增益为指标,分析了全频带、部分频带和单频干扰对这两类扩频码的干扰效果,并进行了比较,所得结论对于直扩系统的设计和研究有重要意义。Direct sequence spread spectrum（DSSS） systems is widely used in practice because of its good performance of anti-jamming,the pseudonoise codes used in these systems have continuous or discrete power spectrum. The process gains act as the index,the jamming effect on these two kinds of spread spectrum code are analysed and compared of three jamming patterns, that are the full band,part band and single band jamming. The results are important to the design and research of DSSS systems.

关 键 词：直扩 干扰 增益 功率谱
