基于高阶累积量的滑动加窗参数型多径时延估计

针对传统方法不适合估计多径时延和难以抑制相关高斯噪声,构造了基于高级累积量的滑动加窗参数估计模型。该模型利用高阶累积量抑制高斯噪声,应用滑动窗充分利用采集数据。通过理论分析和仿真实验表明,该方法能够准确地估计时延,有效地抑制干扰和相关噪声的影响,且在性能估计方面,优于传统基于相关的方法。

Multipath Time Delay Estimation Based on Moving Window Using Higher Order Cumulants

As traditional methods are not suitable to estimate multipath time delay and restrain correlative Gaussian noises,the multipath time delay estimation model based on moving window using higher order cumulants is established.Higher order cumulants are used to restrain Gaussian noises and the moving window is used to utilize data adequately.Theoretical analysis and simulation experiments indicate that multipath time delays are precisely estimated with this method,the disturbances and noises are refrained effec...
