Analysis of Narrow-Band Interference Suppression in DSSS
摘要
Abstract
Building a complete model of direct sequence spread spectrum system (DSSS) by Simulink to discuss the strong narrow-band interference ( NBI) , an improved interference suppression algorithm with lapped transform is analysed. Overlap windowing is adopted to reduce the spectral leakage associated with truncation and lessen the SNR degradation due to windowing. Simulation results show that this algorithm can effectively suppress the strong NBI and improve the BER performance and the interference suppression capability of the system.关键词
