Abstract

Abstract

To deal with wideband band Direction Of Arrival (DOA) estimation in the presence of impulsive noise and co-channel interferences, a novel method is proposed with the help of Cyclic CorrEntropy (CCE) and sparse reconstruction. Firstly, the received signal model of wideband sources is analyzed and a virtual array output is constructed, which shows resistance to impulsive noise and co-channel interferences via the characteristics of CCE. Then, to extract the DOA of wideband signals, the virtual array output with a sparse structure is represented and the Normalized Iterative Hard Thresholding (NIHT) is utilized to solve the sparse reconstruction problem. Comprehensive simulation results demonstrate that the proposed method has efficient suppression on impulsive noise and co-channel interference and it can improve both accuracy and efficiency than existing methods.
