| 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。

| Abstract: | 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. |
