It is assumed that each user is equipped with a single antenna, whereas the base station (BS) has multiple antennas and use zero\u2010forcing (ZF) decoder for multiuser detection. Since each user has an independent oscillator, the received uplink (UL) signal at each BS antenna is corrupted by all of these independent PNs. Furthermore, there may be power imbalances and correlations (due to common scatterers) between different users. These impairments are jointly analyzed in this work. A closed\u2010form expression of the mean square error (MSE) performance of the multiuser MIMO\u2010OFDM system is derived. The analytical results are verified by simulations.<\/jats:p>","DOI":"10.1155\/2018\/3650307","type":"journal-article","created":{"date-parts":[[2018,2,8]],"date-time":"2018-02-08T23:31:35Z","timestamp":1518132695000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Uplink Multiuser MIMO\u2010OFDM System in the Presence of Phase Noises, Power Imbalance, and Correlation"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3151-1690","authenticated-orcid":false,"given":"Xiaoming","family":"Chen","sequence":"first","affiliation":[]},{"given":"Andreas","family":"Wolfgang","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2579-9002","authenticated-orcid":false,"given":"Tommy","family":"Svensson","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2018,2,8]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/35.54342"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2017.2774808"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10762-016-0251-3"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2017.2740206"},{"key":"e_1_2_8_5_2","unstructured":"http:\/\/www.3gpp.org\/."},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1002\/bltj.2015"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/MAP.2016.2630020"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2017.2698780"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/TEMC.2017.2657122"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/temc.2013.2239636"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/LCOMM.2005.1496581"},{"key":"e_1_2_8_12_2","doi-asserted-by":"crossref","unstructured":"LiJ.andWuW.
