Fixed-Threshold One-Bit Toeplitz Covariance Estimation under Sparse-Ruler Sampling
Zhiyong Cheng, Shengyao Chen
We estimate the Toeplitz covariance matrix of a centered Gaussian distribution from data that are both coarsely quantized and sparsely sampled. Only the coordinates of a sparse rul…

Direction Finding of Electromagnetic Sources on a Sparse Cross-Dipole Array Using One-Bit Measurements
Zhiyong Cheng, Shengyao Chen, Qibin Shen +2
Sparse array arrangement has been widely used in vector-sensor arrays because of increased degree-of-freedoms for identifying more sources than sensors. For large-size sparse vecto…
