Furthermore, the known entries are noisy modeled through additive independent random variables with strictly sub-Gaussian distribution, $\textsc{S}\textsc{ub}(c^2(d))$ with a bounded constant dependent on the distance $d$ between the microphone pairs. In this report, we exploit matrix completion approach to recover the full distance matrix. We derive the theoretical guarantees of microphone calibration performance which demonstrates that the error of calibrating a network of $N$ microphones using matrix completion decreases as $\mathcal{O}(N^{-1/2})$.}, pdf = {https://publications.idiap.ch/attachments/reports/2014/Taghizadeh_Idiap-RR-20-2014.pdf} }
