In this paper, we develop a robust constrained-LMS (RCLMS) algorithm based on worst-case SINR maximization. Our algorithm belongs to the class of diagonal loading techniques, in which the diagonal loading factor is obtained in a simple form and it decreases the computation cost. The updated weight vector is derived by the descent gradient method and Lagrange multiplier method. It demonstrates that our proposed recursive algorithm provides excellent robustness against signal steering vector mismatches and the small training data size and, has fast convergence rate, and makes the mean output array signal-to-interference-plus-noise ratio (SINR) consistently close to the optimal one. Some simulation results are presented to compare the performance of our robust algorithm with the traditional CLMS algorithm.<\/jats:p>","DOI":"10.1155\/2015\/458521","type":"journal-article","created":{"date-parts":[[2015,5,6]],"date-time":"2015-05-06T21:02:23Z","timestamp":1430946143000},"page":"1-8","source":"Crossref","is-referenced-by-count":1,"title":["Robust Recursive Algorithm under Uncertainties via Worst-Case SINR Maximization"],"prefix":"10.1155","volume":"2015","author":[{"given":"Xin","family":"Song","sequence":"first","affiliation":[{"name":"Engineering Optimization and Smart Antenna Institute, Northeastern University at Qinhuangdao, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Wang","sequence":"additional","affiliation":[{"name":"State Grid Ningxia Information & Communication Company, Great Wall East Road, No. 277, Xingqing District, Ningxia 750000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinkuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Engineering Optimization and Smart Antenna Institute, Northeastern University at Qinhuangdao, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingguo","family":"Ren","sequence":"additional","affiliation":[{"name":"Engineering Optimization and Smart Antenna Institute, Northeastern University at Qinhuangdao, Qinhuangdao 066004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"1998","key":"1"},{"issue":"5","key":"2","first-page":"599","volume":"ap-24","year":"1976","journal-title":"IEEE Transactions on Antennas and Propagation"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/78.815495"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/TASSP.1986.1164975"},{"year":"2005","key":"5"},{"year":"1980","key":"6"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/8.202711"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/78.285650"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/lsp.2003.819354"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/7.7181"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2003.812831"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2004.831998"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2007.911498"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2011.2169061"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2014.011014.130437"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2010.5403537"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/78.330354"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/78.875480"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2014.2367452"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/78.558478"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1109\/5.622504"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/tsp.2002.806865"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2003.815395"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1049\/iet-spr:20070162"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.2006.886473"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.914347"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1016\/S0047-259X(03)00096-4"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/458521.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/458521.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/458521.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,15]],"date-time":"2020-05-15T05:48:46Z","timestamp":1589521726000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2015\/458521\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":27,"alternative-id":["458521","458521"],"URL":"https:\/\/doi.org\/10.1155\/2015\/458521","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"type":"print","value":"2090-0147"},{"type":"electronic","value":"2090-0155"}],"subject":[],"published":{"date-parts":[[2015]]}}}
