Liping Teng, Qing Wang, Hua Chen · IEEE Communications Letters · 2021
In order to take advantage of the non-circularity property and low hardware cost and consumption of 1bit quantization in DOA estimation, in this letter, we propose a 1bit DOA estimation algorithm for strictly non-circular signals with non-circularity property. The relationship between approximated covariance without quantization and 1bit quantized covarince matrix, 1bit quantized pseudo covarince matrix is further derivation and obtained based on arcsin law. The approximated covariance can achieve DOA estimation via rotational invariance techniques (ESPRIT) type and gridless methods, simulations are provided to demonstrate the effectiveness of the proposed method.
