53577 相对于普通的 SBP 算法,文章所提改进型 SBP 算法是传统置信传播收敛速度的两倍,并且在保持性能的同时降低复杂度。 Compared with the plain shuffled version, the proposed scheme has the same convergence rate which is twice as the conventional belief propagation, and can reduce complexity without any performance degradation.

53582 为了解决传统宽带信号 DOA 估计在全频段作谱峰搜索所得空间谱分辨率较低和计算量非常大的问题, For the DOA estimation of broadband signal, it is required to scan in full band, which degrades the resolution and increases computing load.
53583 新算法采用 FFT 变换,仅仅通过采用选取的部分频带数据进行基于子空间的空间谱估计, Then the proposed approach utilizes only a few sub-bands of the selected narrow band signals to finish the special spectrum estimation based on FFT transformation.
