A research on the algorithms of narrowband interference suppression in DS-SS systems

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.
