This paper discusses a signal subspace based blind adaptive multiuser detector and a Kalman filtering blind adaptive multiuser detector. Combining them together, a new Kalman filtering blind adaptive multiuser detector based on a tracking algorithm of the signal subspace is proposed. Analysis and simulation show that the proposed blind multiuser detector achieves better suppression of multiple access interference and has a higher convergence rate.<\/jats:p>","DOI":"10.3390\/info6010003","type":"journal-article","created":{"date-parts":[[2015,1,20]],"date-time":"2015-01-20T12:36:22Z","timestamp":1421757382000},"page":"3-13","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Kalman Filtering Blind Adaptive Multi-user Detector Based on Tracking Algorithm of Signal Subspace"],"prefix":"10.3390","volume":"6","author":[{"given":"Liqing","family":"Zhou","sequence":"first","affiliation":[{"name":"School of Electronic Information, Wuhan University, Luojiashan, Wuhan 430072, China"},{"name":"Department of Electrical and Computer Engineering, University of Calgary, 2500 University Dr N.W., Calgary, AB, T2N 1N4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry","family":"Leung","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Calgary, 2500 University Dr N.W., Calgary, AB, T2N 1N4, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Electronic Information, Wuhan University, Luojiashan, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guobao","family":"Ru","sequence":"additional","affiliation":[{"name":"School of Electronic Information, Wuhan University, Luojiashan, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quansheng","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Electronic Information, Wuhan University, Luojiashan, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Da","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Electronic Information, Wuhan University, Luojiashan, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,1,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"124","DOI":"10.1109\/35.544334","article-title":"Multi-user detection for DS-CDMA communications","volume":"34","author":"Moshavi","year":"1996","journal-title":"IEEE Commun.
