摘要：
A new Higher Order Statistics (HOS) and Cenetic Algorithm (GA)-based inter-ference redection filter is introduced. Compared with the adaptive filters based on second-orderstatistics and gradient algorithm, the HOS and GA-based filter can reject the interference moreefficiently, is independent of uncorrelated Gaussian noise, tends to converge to the optimum so-lution and is much less sensitive to the choice of the step size parameter. Computer simulationsshow that the method can reject narrowband interference efficiently.
