Localization of Near Field Cyclostationary Source Based on Fourth-Order Cyclic Cumulant

摘要：

A vast majority of the existing eigen decomposition based localization schemes invoke the plane-wave assumption when estimating the localization parameter of multiple sources.When the sources are located close to the array,these techniques may no longer perform satisfactorily.Most modulated communication signals exhibit cyclostationarity.In this paper a new algorithm for near-field sources localization is presented based on fourth order cyclic cumulant matrix and MUSIC algorithm.The algorithm can estimate bearing and range of near field non-Gaussian cyclostationary sources through a uniform linear array (ULA) and remove cyclostationary interference with different cyclic frequency from the desired signals and suppress the cyclostationary Gaussian white noise.Simulation results attesting for the performance of the algorithms were provided.
