In particular we study frame and Riesz basis properties. We apply these results to sets of irregular translates of a bandlimited function $h$ in $L^2(\\R^d)$. This is achieved by looking at a set of exponentials restricted to a set $E \\subset \\R^d$ with frequencies in a countable set $\\Lambda$ and multiplying it by the Fourier transform of a fixed function $h \\in L^2(E)$. Using density results due to Beurling, we prove the existence and give ways to construct frames by irregular translates.", "revisions": [ { "version": "v3", "updated": "2011-11-24T21:45:53.000Z" } ], "analyses": { "keywords": [ "multiplication", "irregular translates", "riesz basis properties", "fourier transform", "construct frames" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1004.1429B" } } }
