| 摘 要： | 针对DS—SS系统未知且统计特性不易获得的窄带干扰，基于最小二乘的方法，在建立信号模型的基础上提出了一种新的抗干扰方法，并对该方法进行了理论推导和计算机仿真．结果表明，该算法对DS-SS系统抗强窄带干扰具有较好的抗干扰效果，与自适应线性滤波算法相比，抗干扰性能更好． |

| Abstract: | A LS-based method of interference suppression was proposed when the narrowband interference occurred and its statistical characteristics was not obtained easily in an unknown DS-SS system. Based on the signal model, the method was analyzed theoretically and simulated .The simulation results show that the performance of the algorithm to suppress narrowband interference in DS-SS systems is good. Compared with the adaptive linear filter algorithm, its performance of interference suppression is better. |
