| Abstract: | This paper researches the different amplitude narrowband interference suppression in direct sequence spread spectrum communication system and introduces a cascade structure of the notch filter with one-order complex adaptive notch filter as notch cell, and makes a theoretical analysis of the adaptive algorithm for coefficient iteration. Simulation results show that the notch filter can effectively eliminate multiple narrowband interferences, and the cor- responding iterative algorithm has good convergence performance. |
