为了进一步提高直接序列/跳频(DS/FH)扩频系统的抗干扰能力,基于小波包变换结合递归最小二乘算法设计
了一种变换域自适应干扰抑制算法,该算法采用小波包分解定位窄带干扰,递归最小二乘算法抑制窄带干扰。通过蒙特卡
罗仿真分析在增加抗干扰模块后,DS/FH系统工作在准静态时,在不同信噪比条件下抗窄带干扰性能。仿真结果表明:该
算法具有较强的自适应性以及抗窄带干扰能力,其性能优于传统的直接置零法,适用于多音干扰下的恶劣通信环境。(In order to further improve the anti-jamming capability of direct sequence/frequency-hopping spread spectrum system (DS/FH), based on wavelet packet transform combined with recursive least squares algorithm design a transform domain adaptive interference suppression algorithm, the algorithm uses wavelet packet decomposition positioning narrowband interference, narrowband interference suppression recursive least squares algorithm. By Monte Carlo simulation analysis to increase the anti-jamming module DS/FH system work in the quasi-static, in different SNR anti narrowband interference performance. Simulation results show that: the algorithm has strong adaptability and resistance to narrowband interference ability, its performance is superior to the traditional method of direct zero, poor communication environment suitable for multi-tone interference.)
