The main idea is to integrate the truncated sinc into the Farrow structure of a Lagrange filter, in order that a superior FD approximation in the least-square sense can be achieved. Its primary advantages are the lower level of mean-square-error (MSE) over the whole FD range and the reduced implementation cost. Extra design parameters are introduced for making the trade-off between MSE and maximal flatness under different design requirements. Design examples are included, illustrating an MSE reduction of [Formula: see text] compared to a classical Farrow-structured Lagrange interpolator while the implementation cost is reduced. This improved variable FD interpolation system is suitable for many applications, such as sample rate conversion, digital beamforming and timing synchronization in wideband software-defined radio (SDR) communications. <\/jats:p>","DOI":"10.1142\/s0218126619500063","type":"journal-article","created":{"date-parts":[[2018,3,21]],"date-time":"2018-03-21T03:40:32Z","timestamp":1521603632000},"page":"1950006","source":"Crossref","is-referenced-by-count":3,"title":["Maximally Flat and Least-Square Co-Design of Variable Fractional Delay Filters for Wideband Software-Defined Radio"],"prefix":"10.1142","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7866-3061","authenticated-orcid":false,"given":"Haolin","family":"Li","sequence":"first","affiliation":[{"name":"Department of Information Technology, IDLab, Ghent University-imec, Ghent 9000, Belgium"}]},{"given":"Joris","family":"Van Kerrebrouck","sequence":"additional","affiliation":[{"name":"Department of Information Technology, IDLab, Ghent University-imec, Ghent 9000, Belgium"}]},{"given":"Johan","family":"Bauwelinck","sequence":"additional","affiliation":[{"name":"Department of Information Technology, IDLab, Ghent University-imec, Ghent 9000, Belgium"}]},{"given":"Piet","family":"Demeester","sequence":"additional","affiliation":[{"name":"Department of Information Technology, IDLab, Ghent University-imec, Ghent 9000, Belgium"}]},{"given":"Guy","family":"Torfs","sequence":"additional","affiliation":[{"name":"Department of Information Technology, IDLab, Ghent University-imec, Ghent 9000, Belgium"}]}],"member":"219","published-online":{"date-parts":[[2018,10,15]]},"reference":[{"key":"S0218126619500063BIB001","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2010.2085291"},{"key":"S0218126619500063BIB002","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2011.2141310"},{"key":"S0218126619500063BIB003","doi-asserted-by":"publisher","DOI":"10.1109\/TIM.2015.2490378"},{"key":"S0218126619500063BIB005","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-016-0283-x"},{"key":"S0218126619500063BIB008","doi-asserted-by":"publisher","DOI":"10.1109\/26.231921"},{"key":"S0218126619500063BIB013","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2003.809712"},{"key":"S0218126619500063BIB015","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2003.813681"},{"key":"S0218126619500063BIB016","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126605002805"},{"key":"S0218126619500063BIB019","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.875385"},{"key":"S0218126619500063BIB020","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2008.2011598"},{"key":"S0218126619500063BIB021","doi-asserted-by":"publisher","DOI":"10.1142\/S0218126615501169"},{"key":"S0218126619500063BIB022","doi-asserted-by":"publisher","DOI":"10.1080\/00207217.2016.1138520"},{"key":"S0218126619500063BIB026","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2006.872397"},{"key":"S0218126619500063BIB028","doi-asserted-by":"publisher","DOI":"10.1109\/LSP.2007.898856"},{"key":"S0218126619500063BIB029","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-005-0704-8"}],"container-title":["Journal of Circuits, Systems and Computers"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218126619500063","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,22]],"date-time":"2019-09-22T22:40:59Z","timestamp":1569192059000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218126619500063"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,15]]},"references-count":15,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2018,10,15]]},"published-print":{"date-parts":[[2019,1]]}},"alternative-id":["10.1142\/S0218126619500063"],"URL":"https:\/\/doi.org\/10.1142\/s0218126619500063","relation":{},"ISSN":["0218-1266","1793-6454"],"issn-type":[{"type":"print","value":"0218-1266"},{"type":"electronic","value":"1793-6454"}],"subject":[],"published":{"date-parts":[[2018,10,15]]}}}
