| 摘 要： | 窄带干扰条件下,自适应滤波器产生非维纳效应。在分析非维纳效应产生机理的基础上,详细仿真研究了强单音干扰条件下,自适应均衡器的收敛和跟踪性能。通过研究得出了一些新的结论:多径和干扰的功率严重影响自适应均衡器的收敛速度,而干扰的频率对收敛速度几乎没有影响;固定的强单音干扰对自适应滤波器的信道跟踪性能影响较小;慢变的强单音干扰对跟踪性能影响较小,快变的单音干扰将对跟踪性能造成严重影响。

| Abstract: | It has been observed that non-Wiener effects occur when adaptive filter is subject to narrowband interference.Based on the analysis of the mechanism of non-Wiener effects,detailed simulation was made to study the convergence and tracking capability of the adaptive equalizer which was disturbed by strong sinusoid jamming.The results of computer simulation show that the channel condition and the power of the jamming seriously affect the convergence rate,but the frequency of the jamming does not.The fixed sinu... |
