摘要： By introducing cyclostationary theory into the estimation of direction of arrival (DOA), we proposed a novel extended cyclic MUSIC algorithm based on fractional lower order cyclic statistics in impulsive noise. By exploiting both the fractional lower order cyclic correlation and fractional lower order cyclic conjugate correlation, the new method can eliminate both impulsive noises and interferences at the meanwhile. It allows to select desired signals and to ignore interferences in communication system which suppresses the interferences of the same frequency band. Simulation results strongly verify the effectiveness of this method. ? 2012 ICIC International.
