Abstract EN
After establishing the sparse representation of the source signal subspace, we propose a new method to estimate the direction of arrival (DOA) by solving an ℓ1-norm minimization for sparse signal recovery of the source powers.
Second-order cone programming is applied to reformulate this optimization problem, and it is solved effectively by employing the interior point method.
Due to the keeping of the signal subspace and the discarding of the noise subspace, the proposed method is more robust to noise than many other sparsity-based methods.
The real data tests and the numerical simulations demonstrate that the proposed method has improved accuracy and robustness to noise, and it is not sensitive to the knowledge about the number of sources.
We discuss the computational cost of our method theoretically, and the experiment results verify the computational effectiveness.
