One efficient possibility is spatial multiplexing of the transmitted symbols over several antennas. Many different MIMO detector algorithms exist for this spatial multiplexing. The major difference between different MIMO detectors is the resulting communications performance and implementation complexity, respectively. Particularly closed\u2010loop MIMO systems have attained a lot of attention in the last years. In a closed\u2010loop system, reliability information is fed back from the channel decoder to the MIMO detector. In this paper, we derive a basic framework to compare different soft\u2010input soft\u2010output MIMO detectors in open\u2010 and closed\u2010loop systems. Within this framework, we analyze a depth\u2010first sphere detector and a breadth\u2010first fixed effort detector for different application scenarios and their effects on area and energy efficiency on the whole system. We present all system components under open\u2010 and closed\u2010loop system aspects and determine the overall implementation cost for changing an open\u2010loop system in a closed\u2010loop system.<\/jats:p>","DOI":"10.1155\/2012\/826350","type":"journal-article","created":{"date-parts":[[2012,4,22]],"date-time":"2012-04-22T21:02:25Z","timestamp":1335128545000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A System View on Iterative MIMO Detection: Dynamic Sphere Detection versus Fixed Effort List Detection"],"prefix":"10.1155","volume":"2012","author":[{"given":"Christina","family":"Gimmler-Dumont","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frank","family":"Kienle","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Wu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guido","family":"Masera","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,4,22]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCOMM.2003.809789"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2004.837271"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2005.847505"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2008.080206"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2010.2056014"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSSC.2009.2037292"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/TCSII.2010.2058494"},{"key":"e_1_2_10_8_2","doi-asserted-by":"crossref","unstructured":"StuderC.
