Let $x\in\mathcal{M}_{m_2}$ be an odd-size signal and let $\tau>0$. Write $\operatorname{supp}(\widehat{m}_2)$ for the support of the Fourier transform of the second moment, and id…

The multireference alignment problem estimates a $d$-dimensional signal from $n$ shifted noisy copies, using the SDP-based relaxation described in Bandeira et al. Rank recovery con…
