Thus, 4G system design should  pursue both higher\u2010transmission bit rates and higher spectral efficiencies. To achieve this goal, multiple antenna systems are called to play a crucial role.  In this contribution we address the implementation in FPGAs of a multiple\u2010input multiple\u2010output (MIMO) decoder embedded in a prototype of a 4G mobile receiver.  This MIMO decoder is part of a multicarrier code\u2010division multiple\u2010access (MC\u2010CDMA) radio system, equipped with multiple antennas at both ends of the link, that is able to handle up to 32 users and provides raw transmission bit\u2010rates up to 125 Mbps. The task of the MIMO decoder is to appropriately combine the signals simultaneously received on all antennas to construct an improved signal, free of interference, from which to estimate the transmitted symbols. A comprehensive explanation of the complete design process is provided, including architectural decisions, floating\u2010point to fixed\u2010point translation, and description of the validation procedure. We also report implementation results using FPGA devices of the Xilinx Virtex\u20104 family.<\/jats:p>","DOI":"10.1155\/2008\/312614","type":"journal-article","created":{"date-parts":[[2008,2,4]],"date-time":"2008-02-04T15:34:04Z","timestamp":1202139244000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Design and Implementation of a Hardware Module for MIMO Decoding in a 4G Wireless Receiver"],"prefix":"10.1155","volume":"2008","author":[{"given":"Alberto","family":"Jim\u00e9nez-Pacheco","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1ngel","family":"Fern\u00e1ndez-Herrero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"Casaj\u00fas-Quir\u00f3s","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,1,31]]},"reference":[{"key":"e_1_2_9_1_2","unstructured":"4MORE IST project website http:\/\/ist-4more.org."},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/35.642841"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/49.730453"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/26.539767"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/18.748992"},{"key":"e_1_2_9_6_2","doi-asserted-by":"crossref","unstructured":"Fern\u00e1ndez-HerreroA.
