摘　　要：针对AR过程的窄带干扰,本文构建了DS扩频系统多窄带干扰下的信号模型,给出了统一的观测模型,并用线性、非线性滤波方法对其进行干扰抑制。仿真结果表明,所建模型是有效的,而且滤波方法对多个窄带干扰仍有很好的抑制性能,且非线性滤波的性能要优于线性滤波。For narrowband interferences of AR process, the signal model for narrowband interferences in DS-SS is established, and the uniform observation model is given. The linear and the non-linear filtering algorithms is used to suppress narrowband interferences. The simulation shows that the models are effective, the narrowband interferences can be well suppressed through filtering, and besides the performance of non - linear filtering is better than that of linear filtering.
