摘要: 针对脉冲噪声与同频带干扰并存时宽带信号的波达方向(DOA)估计问题，该文提出一种结合循环相关熵(CCE)与稀疏重构的算法。首先，分析了宽带信源的接收信号模型，并利用循环相关熵的性质构造出对脉冲噪声与同频带干扰具有抑制能力的宽带信号虚拟输出阵列。随后对该虚拟输出阵列进行稀疏表示，并通过归一化迭代硬阈值(NIHT)算法进行稀疏重构，从而估计宽带信号的波达方向。实验结果表明，该算法对脉冲噪声和同频带干扰具有很好的抑制作用，并且相较已有算法在估计性能方面有明显的改善。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.
