Robust and sparse M-estimation of DOA
Signal Processing, 2023 A robust and sparse Direction of Arrival (DOA) estimator is derived for array data that follows a Complex Elliptically Symmetric (CES) distribution with zero-mean and finite second-order moments. The derivation allows to choose the loss function and four loss functions are discussed in detail: the Gauss loss which is the Maximum-Likelihood (ML) loss ...

Fast ambiguous DOA elimination method of DOA measurement for hybrid massive MIMO receiver
Science China Information Sciences, 2022 DOA estimation for massive multiple-input multiple-output (MIMO) system can provide ultra-high-resolution angle estimation. However, due to the high computational complexity and cost of all digital MIMO systems, a hybrid analog digital (HAD) structure MIMO was proposed.

DoA Estimation via Unlimited Sensing
2020 28th European Signal Processing Conference (EUSIPCO), 2021 Direction-of-arrival (DoA) estimation is a mature topic with decades of history. Despite the progress in the field, very few papers have looked at the problem of DoA estimation with unknown dynamic range. Consider the case of space exploration or near-field and far-field emitters.
