Maximum A Posteriori Direction-of-Arrival Estimation via Mixed-Integer Semidefinite Programming
Tianyi Liu, Frederic Matter, Alexander Sorg +3
We propose a joint sparse maximum a posteriori (MAP) estimator for DOA estimation from multiple snapshots, reformulated as a mixed-integer semidefinite program (MISDP). This enable…
