摘　　要：为实现对直接序列扩频系统中窄带干扰的抑制,针对传统等抽头间隔时域窄带干扰抑制方法不能适应复杂干扰的问题,设计了一种不等间隔横向滤波器结构的时域窄带干扰抑制方法,采用基于素数间隔的滤波器,实现对复杂干扰信号估计与抑制。仿真及实测结果表明,设计方案可以很好地抑制多种类型窄带干扰,固有损耗小,易于实现,资源占用少。The method of suppressing narrow-band interference of traditional equal tap interval system in time domain can＇t adapt to complex interferences.In view of this problem,this paper proposes an unequally interval lateral structures interference suppression method based on prime number interval in order to implement narrow-band interference suppression in direct sequence spread spectrum system.The results of simulation and measurement show that the design scheme can restrain many kinds of narrow-band interferences,and have such advantages as low inherent loss,easy implementation,low resource occupation,etc.
