In this paper, two new algorithms are developed that exploit CP from their data detection part and employ systolic block Householder transformation recursive least squares (SBHT\u2010RLS) algorithms for channel tracking in multicarrier systems. The new methods are compared with the existing CP exploiting correlation matrix based block RLS (CMB\u2010RLS) channel tracking approach to outline their relative advantages. Aspects of computational complexity and parallel implementation are addressed, and the algorithms are tested in terms of their channel estimation and tracking capabilities. Performance of the algorithms is also evaluated for varying forgetting factor parameter values, constellation size, and word lengths. Floating\u2010point and fixed\u2010point simulations are tailored to illustrate pertinent tradeoffs.<\/jats:p>","DOI":"10.1155\/2012\/452806","type":"journal-article","created":{"date-parts":[[2012,2,15]],"date-time":"2012-02-15T21:01:47Z","timestamp":1329339707000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["CP\u2010Based SBHT\u2010RLS Algorithms for Tracking Channel Estimates in Multicarrier Modulation Systems"],"prefix":"10.1155","volume":"2012","author":[{"given":"H.","family":"Ali","sequence":"first","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2012,2,15]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/79.841722"},{"key":"e_1_2_8_2_2","unstructured":"IEEE Part II: wireless LAN medium access control (MAC) and physical layer (PHY) specifications: high speed physical layer in 5 GHz band IEEE Std. 802.11a-1999 September 1999."},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.898255"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/49.93100"},{"key":"e_1_2_8_5_2","unstructured":"Radio broadcasting systems: digital audio broadcasting (DAB) to mobile portable and fixed receivers ETSI ETS 300 401 1.3.2 ed. 2000."},{"key":"e_1_2_8_6_2","unstructured":"Digital video broadcasting (DVB): framing structure channel coding and modulation for digital terrestrial television ETSI EN 300 744 1.3.1 ed. 2000."},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/35.809389"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.545896"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.380108"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/4234.798021"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2002.807610"},{"key":"e_1_2_8_12_2","doi-asserted-by":"crossref","unstructured":"AliH.andHassan.Ali@newcastle.edu.au LingE.
