Ad hoc microphone array calibration: Euclidean distance matrix completion algorithm and theoretical guarantees
Euclidean matrix completion enables calibration from partial distance measurements. A novel Euclidean matrix completion algorithm is proposed. The relation between error and number of microphones, noise and missing distances is derived. Theoretical insights are demonstrated by thorough experiments on real and simulated data. The performance is compared with SDP, S-Stress, MDS-MAP and Matrix completion.
