摘要:

提出了一种基于MUSIC的小天线阵列波达方向(DOA)估计策略,通过深度学习重构虚拟大天线阵列的信号。所提出的策略不仅提供比简单地将传入信号插入到MUSIC中更好的性能,而且令人惊讶的是,对于高角度范围和低测试SNR值,该性能也优于直接使用具有MUSIC的实际大型天线阵列。我们进一步分析了作为测试SNR的函数的训练SNR的最佳选择,并观察了该函数在不同角度范围内的行为的显着变化。

英文摘要:

We present a MUSIC-based Direction of Arrival (DOA) estimation strategy using small antenna arrays, via employing deep learning for reconstructing the signals of a virtual large antenna array. Not only does the proposed strategy deliver significantly better performance than simply plugging the incoming signals into MUSIC, but surprisingly, the performance is also better than directly using an actual large antenna array with MUSIC for high angle ranges and low test SNR values. We further analyze the best choice for the training SNR as a function of the test SNR, and observe dramatic changes in the behavior of this function for different angle ranges.
