The Bayesian frame work is used to obtain sparse solutions for regression tasks with linear models. By exploiting a probabilistic Bayesian learning framework, sparse Bayesian learning provides accurate models for estimation and consequently equalization. We consider frequency domain equalization (FEQ) using the proposed channel estimate at both the transmitter (<jats:italic>preequalization<\/jats:italic>) and receiver (<jats:italic>postequalization<\/jats:italic>) and compare the resulting bit error rate (BER) performance curves for both approaches and various channel estimation techniques. Simulation results show that the proposed RVM\u2010based method is superior to the traditional least squares technique.<\/jats:p>","DOI":"10.1155\/2010\/191808","type":"journal-article","created":{"date-parts":[[2010,6,29]],"date-time":"2010-06-29T14:36:19Z","timestamp":1277822179000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Relevance Vector Machines for Enhanced BER Probability in DMT\u2010Based Systems"],"prefix":"10.1155","volume":"2010","author":[{"given":"Ashraf A.","family":"Tahat","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nikolaos P.","family":"Galatsanos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2010,6,29]]},"reference":[{"key":"e_1_2_7_1_2","unstructured":"Broadband Forum Next generation broadband access white paper Marketing Report August2009 no. 185."},{"volume-title":"3G Evolution: HSPA and LTE for Mobile Broadband","year":"2007","author":"Dahlman E.","key":"e_1_2_7_2_2"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCOM.1971.1090705"},{"key":"e_1_2_7_4_2","unstructured":"The European Telecommunications Standards Institute Digital video broadcasting (DVB); framing structure channel coding and modulation for terrestrial digital terrestrial television 2001 no.
