Abstract Due to the defects of high complexity and instability convergence performance in the array signal adaptive canceller under the correlated interference, an enhanced array signal multistage cascaded canceller is proposed by substituting the weights of the multistage Winner filter for the minimal module weights, which have the minimal module of the samples quotient between channels. The enhanced algorithm has the ability of fast convergence, less operation and performs well with non-stationary samples distorted by the correlated interference. Simulation results indicate the algorithm can reach convergent performance of the kind of Sample Matrix Inversion (SMI) algorithm using less samples.
