Elimination of pulse-noise from mixed-noise based on fractional lower order ICA by QIU Tian-shuang1, LI Bing1, ZHA Dai-feng2

“…In order to solve the problem that traditional denoising methods based on the second order statistics were usually degraded in their performance when the received signal was contaminated by both Gaussian and Alpha stable noises.A fractional lower order statistics based ICA method was introduced.It eliminated the pulse noise from the mixed noise first,and then removed the Gaussian noise with the SVD method.The simulations show that the new method is effective on the noise elimination,and the pure signal in the received signal is not deteriorated.…”

Fractional time delay estimation method based on the minimum CIM and the Farrow structure by ULing Y, IUTian-shuang Q

“…A fractional time delay estimation algorithm is proposed which is based on the minimum CIM and the Farrow structure (referred to as MCIMFarrow).The proposed MCIMFarrow algorithm performs well in symmetric Alpha stable noise conditions.And it needs little observation data to gain high accuracy estimation results.The theoretical analyses and the simulation results show that the MCIMFarrow is much better than the LETDE algorithm based on the fractional lower order moments in the accuracy of the time delay estimation and the robustness in impulsive noise conditions.…”
