Deterministic maximum likelihood method for direction-of-arrival estimation of strictly noncircular signals

Yunmei Shi, Xingpeng Mao, Mingyang Cao, Yongtan Liu

ICASSP 2016accepted

In this paper, a noncircular deterministic maximum likelihood (NC-DML) estimator for direction-of-arrival estimation of strictly NC signals is devised. Unlike the conventional DML solution for arbitrary signals, the NC-DML exploits the NC properties of the sources by reconstructing the parameter set…

Joint direction-of-arrival and frequency estimation without source enumeration

Cheng Qian, Lei Huang, Yunmei Shi, Hing-Cheung So

ICASSP 2015accepted

Joint estimation of the directions-of-arrival (DOAs) and frequencies of multiple signals is addressed in this paper. By constructing a set of joint diagonalization matrices, two cost functions that do not require a priori information of the source number are devised for DOA and frequency estimation…
